This one is for the Rockola crowd. I have heard the M1 Rockola carbine is considered a rare find. This one has the Rockola reciever but an underwood barrel. Overall it is a good looking rifle. I think I am going to pick this one up along with an M1 paratrooper carbine with matching reciever and barrel manufacturers. Both are going for $750 a piece. I know it is hard for anybody to value these rifles with the little info I have given. What should I look out for?
