This lever action repeating rifle was made by the Evans Rifle Manufacturing Company of Mechanic Falls, Maine between 1873 and 1879.  It is believed that about 3000 were made for the military market and sold to Turkey, Russia and possibly others.  Apparently, some of these military muskets were designed to accept a socket bayonet and some were designed to except a brass hilted sword bayonet.  The number designed for just the sword bayonet is unknown. 

An advertisement published for the Evans Rifle found on https://www.gunboards.com/threads/evans-bayonet.452729/ shows a drawn picture of the Military Musket with both socket and sword bayonets below the musket.  Clearly the sword bayonet has a ribbed brass hilt similar to those listed in this study.  

The actual diameter of the musket's muzzle is still uncertain but believed to be slightly larger than 18 millimeters.  But, both muskets and carbines were produced as well as different cartridges, .44 Evans and .44-40. There may be differences in the muzzle diameter as well.

Actual details of the bayonet for this variation is currently uncertain but may be similar to Reference #308.

The similarities of the bayonets produced for the Remington, Whitney and Evans muskets are similar and absolute identification is difficult.  The associated bayonet variations listed below are only possibilities for this musket.
