This Rogers Swivo-matic pedal came with my '72 Pearl set and by default have used it as my gigging pedal since '75. I've always loved playing it. I recently pulled my drum gear from storage and did a cosmetic rehab on my Pearl set that includes this pedal. Kindly have a look at the pedal and let me know your thoughts. I have little knowledge of Rogers gear. I'd like it to be totally original. Is there a formal name and model number for this pedal---and from what year? Obviously before 1975 when my parents bought it for me.

In the close up, I know the screw holding the beater is not the correct one, but do you Rogers guys know what it is and where I can purchase one? Also, I'm skeptical of the screw/washer that holds the underside of the pedal to the base. Please advise.

Also, is the beater, washer and nut atop the beater pole correct? Help2

Thanks ahead of time. I'd like this pedal to be 100% totally period correct.
