I was just given not less then 2 hours ago a new shotgun. the shotgun is not new but for me it is basicly. it was my dads from a long long time ago. it has sat in a storge space for a long time, he figured i would like it an take care of it better then it had been so far. so i was looking for a break down an a manual for this firearm. but my problem is he said it was rare. it is a Stevens Model-940A Savage Arms single shot 20. gauge all i could find online is a is the 940-Y, which i guess is the more modern version. i did find one person selling his 940A but i cant find a manual or a breakdown for it so i was wondering if anyone here could help me at all. he said it might be from around 1930-1940. it was i guess there prototype into like a ladies shotgun for lack of better words. if theres anything else you'd wanna know so i can help you help me i can share. i think i covered all bases. thanks in advance for any help.
