I used to collect Winchester M42 and M12 shotguns. Then I got tired of it and stopped. Be very careful if you get into M70 rifles - there are a lot of frauds running around. You might want to contact the Buffalo Bill Historical Soceity in Cody - they have the Winchester mueseum there now and find out what records have been preserved to help verify your potential purchases. I never got into M70's - I hope the records are better than those available for M12/M42 guns. Most of those were burned years ago.
