The Winchester Imperial aka the Model E or the Model 51. This is one of the rarest Winchester models made with only 24 produced. The Model E was the fifth in a development series that led to the Models F and G, better known as the Models 54 and 70, respectively. The whole series (starting with the Model A in 1913) was influenced by Mauser actions, including the 1903 and the P14/M1917. Even modern production Model 70s have roots in these guns. This rifle is number three and bears the caliber designation “.27 Cal”, chambered in what we now know as .270 Winchester. One of three Imperials in the collection, this one was probably made in early 1919.
