I have read that in the late 50's/early 60's Camco had made products for Rogers and that they also produced the "Floating Action" pedal for Gretsch which was practically the same as the Camco "Deluxe" pedal except for the foot board.

However, I'm hoping some experts out there might be able to shed some light on their tension rods, which look pretty identical.

Perhaps Camco was also machining these for Gretsch as well?

They both share the similar taper just under the collar.
