I have recently come into possession of what claims to be a Bor Yueh front carrier. What I really have, of course, is a fine collection of bent and welded alloy rods, and a little packet of assorted bolts, nuts, and bent and perforated bits of steel. I think I have most of the assembly sussed, but the thing that bothers me is a pair of alloy collars about a quarter of an inch long.
Anyone have any bright ideas about where these are meant to go?
