I acknowledge that a photo would be more helpful than my attempt at a description, but... I just received a parstcaster, which seems to have been assembled in the very early eighties (although the bridge looks to have been switched, at some point). Its bridge is a dead ringer for a seventies, one-piece Strat vibrato bridge, except that neither the saddles nor the block have part numbers stamped into them. The saddles (otherwise identical to 70s Strat parts) have a stamped "F-in-a-circle" on the back, below the string slot. They're magnetic - steel, I guess. The block is chrome plated, except for its bottom surface. Probably some kind of pot metal. The bass side of the block is flat, while the treble side is rounded, like a typical Fender, and it has shallow string holes. Has anyone encountered a bridge like this? An import of some sort?
