Ah OK thanks a lot. Something like a semi-permanent glue could solve that problem quite easily I'd have thought. If I find the same when I get mine I might dry a dab of "Fendermender" (shoo-goo) on the pin.
EDIT: Just seen your edit. As far as I am aware, HB don't make an MIP Steel bone, so you'd have to use the universals. I don't have the part numbers to hand, but a quick search on the HB Europe site (
www.hbeurope.com) should work.
