You may have the last remaining unbroken L-77 . . . and when you "bend it back" it'll most likely break, as I believe it's a casting. Find the guy who did it, ask him if he's left of right handed, and break off which ever hand he names. I thought someone was making / fabricating a replacement but can't remember or find who . . . Someone will "pipe in".
