Why do so many think that the Winchester Model 1876 was simply an evolution of Winchester’s Model 1873?
In this, the 150th anniversary year of the Winchester 1876 “Centennial Model,” we’re presented with a fine opportunity to revisit that assumption by sharing some fascinating research conducted by renowned authors.

Because once we begin following their documentary record rather than the familiar shorthand, the story of the Model 1876 becomes far more interesting and far less linear than commonly told.

The root of the misconception can be traced, quite fittingly, to Winchester itself.
At the Philadelphia Centennial Exposition of 1876, the company launched its new big frame rifle with promotional language that was clear, confident, and commercially sensible. The brochure famously stated:
“The success attending the sale and use of Model 1873 and the constant calls from many sources, and particularly from the regions in which the grizzly bear and other large game are found, as well as from the plains where the absence of cover and the shyness of the game require the hunter to make his shots at long range, made it desirable for the Company to build a still more powerful gun.
Retaining all the essential mechanical elements of the former model, and adding such improvements as seemed possible, the result has been a gun carrying a central fire cartridge, capable of reloading, caliber .45/100, with 75 grains of powder and 350 grains of lead, being nearly double the charge used in Model 1873, and about the same as that adopted by the U.S. government.”
It’s difficult to fault the public for taking this at face value. When the maker of the rifle tells you it retained the essential mechanical elements of the former model, the natural conclusion is simple. The Model 1876 must be a larger, more powerful Model 1873. That tidy explanation has endured for a century and a half because it’s convenient (the ‘76 is in fact larger and more powerful than what happened to come before), memorable, and plausible enough to pass without challenge.
A closer examination of Winchester’s developmental path, however, suggests that the rifle we now call the “Centennial Model” didn’t truly originate with the Model 1873 at all. Its intellectual and mechanical origins can be traced back roughly twelve years earlier, to a period when its predecessor company was still grappling with the limitations of the Henry Rifle, long before the Model 1873 had even entered serious consideration.
To understand the Model 1876 properly, one must begin not in 1873, nor even in 1866, but in 1864.

Before we get too much further, a word of acknowledgment and gratitude.
This article, and the research behind it, stands on the shoulders of the late Herbert G. Houze (1947–2019), a renowned firearms historian whose scholarship on the Winchester Repeating Arms Company, Colt’s Manufacturing Company, and European arms earned international respect. Named Curator Emeritus of the Cody Firearms Museum, Mr. Houze left behind essential reference works that continue to guide collectors and historians alike.
In his landmark volume, The Winchester Model 1876 ‘Centennial’ Rifle (2001, R.I. Andrew Mowbray Inc., Publishers), Mr. Houze himself credited the foundational, and perhaps game-changing, research of Lou Behling. Mr. Behling, a leading authority on rimfire cartridges and small arms ammunition, demonstrated that efforts to improve the Henry Rifle began before 1865, challenging long-held assumptions. His work reframed the developmental timeline and opened the door to a deeper understanding of the Model 1876’s true origins.
Because of scholars like Houze and Behling, we can see the Centennial Rifle not merely as a “bigger 1873,” but as the product of a longer, more deliberate evolution.

As Mr. Behling followed the paper trail back to 1864, he found record of three modified Henry breechloading carbines sent by the New Haven Arms Company to the U.S. Ordnance Department for serious evaluation.
These weren’t off-the-shelf Henry Rifles. They were altered breechloading examples with magazines, widely believed to have been refined by mechanic and designer Luke Wheelock in the New Haven model room. They were put through formal trials at Springfield Armory between March 18 and March 30, 1864. Major A.B. Dyer forwarded the results to Brigadier General George D. Ramsay, including detailed sub-reports from Master Armorer Erskine S. Allin and Captain William S. Smoot. Later that year, a similar carbine was tested again at the Washington Arsenal by Second Lieutenant H. Stockton.
The verdict was consistent and sobering. Mr. Houze takes up the story from here.
Allin noted multiple failures under careful handling and questioned the durability of the loading system. Smoot focused on the extractor and concluded it was poorly designed for service use. Stockton, months later, arrived at much the same opinion. In short, the magazine repeater principle impressed, but the execution did not. The rifles were clever. They were not yet rugged.
What makes these 1864 carbines especially interesting is that they were already evolving. They featured detachable sideplates and other construction details that suggest New Haven Arms was experimenting with stronger, more accessible mechanisms. These were early steps toward something more substantial.
The Ordnance Department’s criticism didn’t kill the idea of a repeating rifle. If anything, it sharpened it. The magazine concept survived and would soon be protected by patent. But the message was clear. If a repeater was ever going to be taken seriously for military or hard frontier use, it would need better extraction, stronger construction, and ultimately more powerful ammunition than the .44 Henry rimfire could provide.
That realization in 1864 is where the true story of the Model 1876 begins.

What followed was not a straight line, but a sustained engineering conversation inside Winchester’s model room. Nelson King’s 1866 loading gate and sealed magazine tube solved the practical deficiencies revealed by the trials.
Swiss and British contract rifles of 1866 and 1868 respectively, as well as experimental iron-frame receivers, quietly explored stronger constructions and larger centerfire calibers.
The late-1860s experiments of Luke Wheelock, driven as much by the demands of buffalo hunters as by military curiosity, tested the very limits of the toggle-link system and exposed exactly how far it could be “up-armored” before it reached its ceiling.

In this light, the Model 1873 appears in a different role than it is often assigned today. Rather than the parent of the 1876, it’s better understood as a necessary bridge: an iron-framed, centerfire-capable successor to the declining rimfire 1866.
The ‘73 kept Winchester commercially viable while the company continued its far more ambitious pursuit of a true big-bore repeater. The ’73 solved immediate market needs in light of flagging .44 rimfire demand, but it didn’t solve the larger problem of power.

That larger problem demanded a parallel evolution of rifle and cartridge alike. By the mid-1870s, Winchester’s engineers weren’t merely scaling up an existing arm; they were balancing mechanical limits, metallurgy, extraction reliability, and ballistic expectations. This was in an era increasingly defined by the .45-70 Government and the realities of big game hunting on the plains.
The result was the .45-75 Winchester Center Fire, a cartridge deliberately shaped to deliver reliably from a toggle-link action while still presenting itself as a serious hunting round. It wasn’t an afterthought. It was a co-equal design partner to the rifle that would fire it.

When the new big-frame rifle debuted at the Philadelphia Centennial Exposition in 1876, Winchester’s own promotional language understandably framed it as a more powerful continuation of the Model 1873. That narrative was tidy, marketable, and easy to grasp. It also proved enduring.
Yet beneath that convenient shorthand lay twelve years of iterative development, experimental receivers with detachable sideplates, abandoned breechblock concepts, and repeated attempts to reconcile repeating fire with true big-bore performance.

By the time the first production rifles reached Winchester’s shipping department in June of 1877, the so-called “Centennial Model” represented the culmination of lessons learned since the closing years of the Civil War.
Its architecture, its cartridge, and even its intended role in the marketplace had been shaped by the failures of 1864, the innovations of 1866, the experimental contracts of the late 1860s, and the power crisis of the frontier hunting boom.
Seen in this context, Mr. Houze posits that Winchester’s Model 1876 stands not as a simple enlargement of the Model 1873, but as the logical descendant of the Henry Rifle’s unresolved ambitions. The ’73 kept the lineage alive during a transitional moment. The ’76 fulfilled the original quest: a reliable repeating rifle of meaningful power, purpose-built for larger game, longer distances, and a rapidly changing world that demanded more than capacity alone.
In other words, the true road to the Centennial Rifle does not run from 1873 forward. It runs from 1864 onward—through trial, criticism, experimentation, and persistence—until Winchester finally arrived at a rifle and cartridge designed together, each pushing the other to the very edge of what the toggle-link system could achieve.
Thank you for publishing this piece of history. Like many, always thought the 76 was just a larger version of the 73 to handle longer cartridges. Very interesting.
Thank you for reading, Mr Sas. The research going back to 1864 is eye-opening indeed. We’re grateful for the work of Mr Houze and Mr Behling.
