Going through stuff I need to get rid of, and I found a box with a bunch of M1 slings in it. Over the years, I collected a lot of CMP rifles, and the slings probably came with them. Most of them are worn an are a khaki color but they do have some interesting markings on them like the one has a crown on it another some numbers. Some have magic marker and paint on them. Most are pretty worn. My question is do people collect these or would they want to buy them or should I just pitch them in the dumpster?
