the bottom picture in this link \/ has armourers drawings of the LEC bolt handle for anyone considering having this done.

note it has drawings of the LEC 5 round magazine as well, not really applicable for a BSA but maybe for a LSA built lee speed.

I have talked to my gunsmith of choice about reshaping the handle and he wasn't willing to do it... eventually i'll have to find one I trust, who will.
