I am looking for a sling and oiler for my 1950's era IBM M1 Carbine. I have tried one website that sells reproductions, but the item gets very poor reviews, including one that stated the sling and oiler did not fit the customer's IBM M1. My questions is...is there a website or company that I can find a sling and oiler that would fit my M1? Is does not matter if it is original or a replica. As always, any information is appreciated.
