I'm glad I found this forum. It seems that the documentation on this rifle wasn't well preserved. I'm just glad I'm not the only one. I have my Winchester 190 that I learned to shoot with a very (very) long time ago. It was left to me by my Grampa when he died and it is in excellent shape. I just don't have a clue how to break it down to make sure it stays that way. It's driving me crazy! I mean I can usually figure out how to break down any rifle (course somnetimes I can't get back together). Anyway, Please send me any disassembly instruction that you can. It would be greatly appreciated.
