Winchester 1917 question.

That 3-GMK is probably an Inland/Guide Lamp WW2 rebuild mark

I think ChuckinDenver is right on the money as far as i would be concerned. Its easy to give a estimate but another if you ask them if they would offer that much. Chuck G

Thanks a lot. How difficult are these rifles to take apart?

not hard at all, but if you not done one, it can be tough...maybe have the gunsmith walk you through that..if you lived here close, i would do that for you...
