This appears to be a side ejecting prototype of a slide action carbine similar to a Winchester Model 1894 lever action. The receiver is devoid of markings and shares visual similarities with Marlin lever actions with its side ejecting port but appears to have a Model 1894 loading gate and takedown screw at the front bottom, taking down in a similar manner to other Winchester slide actions. The barrel, magazine, and barrel band appear very similar to a Model 1894 carbine. The barrel has the two-line Winchester address on top and two-line nickel steel marking on the left. Interestingly it is fitted with King blade front and elevation adjustable buckhorn rear sights even though the tag attached to the buttstock is marked "PROP. OF REDFIELD/152/GUNSIGHT CO. DENVER". It is mounted with a five-groove slide handle and checkered straight grip stock with a shotgun buttplate.

Fine as likely a one of a kind prototype, retaining 70% of the blue finish with the balance mostly a smooth grey patina with some scattered patches of brown. The wood is also fine with a couple repaired cracks in the slide handle, minor dings and scratches scattered throughout, and a light speckling of silver paint near the tag on the buttstock. Appears to function as it should.
