My latest find, a .45 caliber that I believe is an early Jukar, now looks pretty good except for the one hole thru the (full) stock for the pin to retain the barrel. The outside(s) of the hole is oversize, so though the pin fits well the visible ends of the pin are "lost" in the hole(s). I'd like to fix it. How should I go about it? Change the tenon on the barrel for a wedge instead of a pin? Make brass escutcheons for the pin? What say ye?
