This early Winchester pocket knife was manufactured over 100 years ago as a prototype for a model which was never released. Closed length is approximately 3 and 3/4". As far as I know, this is a one-of-a-kind piece and was the only prototype ever made for this model. Every blade on this knife is engraved with the Winchester logo. Our family has had this piece for over 35 years, and got it from an old man who told us it's been in his family for 85 years. (He was close to 90 at the time we got it, and he told us his father worked for Winchester.)We've been collecting knives for over 45 years and have never seen another one like it. Every collector we've ever shown this to has never seen one like it either. (NOTE: This is NOT a Boy Scout knife!)
