These were used on Electrolux metal canisters from 1205 to Super J canisters.
The axle diameter is 1/4" as opposed to the Olympia One & later which is 5/16".
markings on them are 5135-27. These are for the skinnier wheels.
Pleae make an offer. They are original Electrolux that I painted black.
These are made from pot metal which is why so many are broken.
I have special stainless screws & nuts I use when replacing them if you need them (small charge)
