Fellow Shooter at my club asked me if I could help him find a mag for his BSA, I went to Big gunshows in Kamloops and the really big Calgary show year after year and found nothing.
3 years later I go to my local show and I see one, seller has no tag or price on it.
I told him what it fits and we came up with a 25.00 price. I bought it for my friend and it fit like a glove . He was very happy to get it!
Moral of the story, Go to as many gunshows as you can and keep your eyes open, you never know....
PS: it's not a "Clip" it's called a Magazine.
