All the 4 of these Compur are nice, but something puzzles me, it seems that none of them have the three-dimensional concentric circles in the subdials, the surface is flat...
Now I have about 15 compur from that era and all of them have these concentric circles. As far as I know when you refinish a dial, 95% of the time the three-dimension is altered. Wouldn'd these dials be some old refinish ?
