I picked up this old BSA recently.It is a .22,I think a trainer.Stampings are "made by The Birmingham Small arms co Ld Birmingham 1907"and off to the side of that is "min.Rifle W.O.patt"with a crown.If someone can help me or need to see it I can send pics,but please only if you know BSA and can help.The problem I have is it is missing the bolt.
