I found this Winchester lock back today. When my daughter grew up and left the nest ... she also left a whole bunch of stuff in her old room!! After years of asking her to do something with it all each time she visited ... I finally decided to box, bag and move everything to the attic. While going through here things, found this little Winchester lock back. Have no idea where it came from, nor does she. I am pretty sure I didn't give it to her. So, finding was like New Year's surprise! It has no tang stamps whatsoever. Just the Winchester labeling on the frame and blade. So, have no idea what model it is or time frame it was made. I did, however, give it good sharpening!
