These pedal rubbers are now available. See 2 photos below. There are 8 required for 1 pair of pedals. The price is $80.00 for 8 parts.
I will need 8 metal cores from your pedals. They should be clean no old rubber on or inside. If you are replating the pedals the cores should be plated.
They can not be plated when the rubber is on them.
This style pedal rubber was used on many pedals Queen, King, Banner, Grothe etc. etc. I do not know how many.
