In an old trade many years ago, I acquired a few used barrels of different lengths supposedly for a Crosman. I put them away because I had no use at the time. Several years have passed and I just came back across them. Is there any particular way to ID these barrels? I suppose for checking if I want to know what caliber, I could simply try to see what pellets fit through them easily.
Just thought I would check in case someone had any other thoughts.
Thanks
