Following the Civil War, the federal government was experimenting with adopting some form of breech loading rifle based on the experiences of the war.



Erskine Allin was the master armorer at Springfield, and he developed this conversion design based on utilizing the 1863 percussion rifles left over from the Civil War.

The conversion was designed to take advantage of the sizable quantity of muzzle loading Model 1863 Springfields that were stockpiled following the Civil War. The overall design and philosophy of the conversion (remove a section of the breech, mill a chamber into the barrel, install a hinged breech block) remained consistent through all produced versions of Allin's system.

The first models (left and above) retained the 58 caliber bore, a mechanically ingenious spring loaded extractor/ejector assembly; opening the breech extends a cam-driven extractor, while retracting an ejector pin mounted in the bottom of the cutout, and when the breech is fully opened the extractor snaps back and the pin strikes the extracted cartridge, ejecting it from the weapon.

The second model, 1865 (below), had a simplified and improved extractor and the barrels being relined and rifled to .50 caliber and chambered for the powerful centerfire .50-70 Government cartridge.




The conversions were significant and key to martial rifle development as it ushered in the trapdoor rifle series and actually brought the US military solidly into the breech loading era. 

Both conversions amounted to approximately 25,000 Springfield Model 1863 rifled muskets that were converted by Springfield Armory for use by U.S. troops.

Trenton Locomotive and Machine Company Model 1861 rifle-musket.



The U.S. Model 1861 Springfield rifle musket was the primary infantry weapon of Federal Forces at the start of the Civil War. 
Springfield Armory could not keep up with the demand for muskets at the start of the war, and sub-contracted to a number of private manufacturers. 

On December 26, 1861, James T. Hodge and Addison M. Burt each received separate contracts calling for 50,000 Model 1861 rifle-muskets at $20.00 each. 
Shortly thereafter Burt approached Hodge with the suggestion of joining their respective arms-making venture, but without forming an actual partnership or corporation which would have voided their contracts. Both felt that a combined effort would prove highly beneficial. 

In mid-January of 1862, Burt and Hodge leased the extensive facilities of the well known Trenton Locomotive and Machine Company, Trenton, New Jersey, at which place they planned to fabricate the rifle-muskets of their respective contracts.

In the following May, Hodge and Burt requested that their contracts be reduced from 50,000 to 25,000 each. This request was approved and so ordered by P.V. Hagner of the U.S. Ordnance Department. 
In spite of the complete and extensive machinery and equipment at their disposal, neither contractor was able to deliver more than about half of their already reduced contracts. Mr. Burt delivered 11,495 rifle-muskets, and Mr. Hodge, 10,500. All were typical Model 1861's in all respects.

The 'Trenton' marked rifle-muskets are excellent examples of a wartime product manufactured through the facilities of what had been a successful peacetime operation, and exemplified the ability of Northern industry to retool for war production." - Reilly

"...many Trenton marked muskets were delivered to the State of New Jersey and perhaps to other states. In 1863 the legislature and governor of the State of New Jersey decided to purchase 10,000 stands of the Springfield rifled musket." - Hartzler, Yantz, Whisker.

The Whitney Model 1861 "Plymouth" Rifle


February 7th, 1856, Commander John Dahlgren requested permission from the acting Chief of Bureau of Ordnance to develop a rifled musket, for Naval use, also to hold trials in order to determine the proper design for Naval service. The "Plymouth" rifle, named after the U.S.S. Plymouth, came into being, after several years of Dahlgren’s persistent efforts.

10,000 of these "Plymouth" rifles were manufactured between 1861 and at the 1864 Whitneyville Armory and Whitney Arms Company under contract with the U.S. Navy.


Dahlgren believed that the short 34” barrel and the .69 caliber was best suited for the Navy’s requirements than the standard 40’ barreled .54 caliber adopted by the Army. The short barrel was better for climbing in and out of small boats, climbing up masts to the ships fighting tops and for boarding and landing actions. The large .69 heavy ball could deal with a ship’s wooden bulwarks plus the larger bore was more amenable to buckshot. He felt buckshot would be better suited for close quarter fighting that sailors would likely be confronted with.

He had little concern about the extra weight of the .69 caliber rifle and ammunition since sailors acting as naval infantry would not normally be called on to make long marches.
Dahlgren also wanted to employ more precise sights suitable for ship to ship sniping. Last but by no means least was the Collins & Company saber type bayonets used only on this model.

The rifles saw use on various U.S Navy warships during the war and were highly sought after. A commanding officer reportedly requested Plymouth rifles in exchange for the Spencer rifles his crew was issued because the harder hitting Plymouth with its distinctive saber bayonet was more useful than the Spencer's rapid fire at close range hand to hand fighting.
Variations are found throughout the Plymouth rifle contract due to Whitney's penchant for using leftover parts from other weapon production runs.
