A customer came to my shop today and amongst his many wants is that he has a very old Lefever "sidelock" and it is missing the forend release button. Said part is 3/4 inch in diameter.Who out there has one and wishes to part with it or knows of someone who will? Thank you. Bill BTW I torch soldered the tip of the Fox barrels as mentioned in an earlier post and the forend loop of a Chain Damascus set of barrels(not mentioned in any post).Brownell's Hi-force.
