I saw this at the flea market last weekend being sold by a dealer in junk jewelry and belt buckles. What caught my eye were the two campaign stars in the middle just below the musket. It looks like these two stars have been on this sterling marked CIB for a while which has the shorter clutch back pins so possibly WW2. The rear of each hole is curdely beveled. There are remnants of blue around the muzzle, hammer and trigger guard. Has anyone come across campaign stars attached to a CIB before?
