Rogers Swiv-o-matic Bass Drum Pedal

Rogers Swiv-o-matic bass drum pedal. All nice and working but with marks as you would expect for a 60 odd year old pedal. The hex grub screw near the beater is a new replacement, the strap is also new. I don't think the beater is original but it is a good beater. The bass drum clamp and the fixing screw were sold to me as new old stock although there is a rust spot on the clamp.
