1 lx 9 months ago TFI. (Total Financial Interest)I'm selling off a '45/6 Synchro 100 here in the Garage Sale, and it came with a strange bridge. I've seen only two other of these models, both with a Synchromatic base and non-compensated saddle. The other two looked generic, but this one has small steps along the sides which match the whole Synchromatic stair-step motif. Has anybody seen anything like this before?
