I was looking for an 1130 movement for parts and came across an unusual example of jeweling for advertisement. Aside from the usual cap jewel, there are an additional 3 jewels simply placed into the gear train plate--looks like one of them was taken out and maybe used as a replacement somewhere? It can also be seen where the original number of rubis was machined off and the number 21 stamped in. I've never come across decoration jewels embedded into the bridge plate!
