I have two Camco pedals... both strap drive that I'm working on. Slight difference. On one the tab that fits on the rotor shaft for the spring to attach two has only two adjusting holes; the other has four. The tab with four holes is also chrome plated.

The two hole tab seems to be a little higher quality metal.

Anyone able to roughly date these? My guess is that the two hole tab is the earlier.

Not a huge question... just curious.
