Antique Neiger Czech Glass Charm Necklace, in my research It makes me confident this is made by the Neiger brothers, it measures about 16 inches end to end, and as far as I can see there are no issues, it seems to be all original, and it is stamped Czechoslovakia on the jump ring, there are 20 charms, and I’ve never seen another one, I’m not saying there isn’t one, I’m just saying I’ve never seen another one and I’m 70 years old
