Norinco JW-14 22 cal semi-auto

This rather unique Norinco semi-auto 22 cal trainer came down from Canada through a distributor in Maine. It looks like a German WWII style rifle with a ladder rear sight and impressive machining throughout. I did have to make a repair to the stock behind the end-cap that in no way affects its function or shootability. I'm told that old high cap Marlin Papoose mags will work in this gun but I haven't tried anything but the original mag that it comes with. Thanks for looking!
