Minolta Weathermatic A 110 O rings (Hither Green SE13)

I have a Minolta Weathermatic A that takes 110 cartridge film. This is a waterproof camera made in 1980. It can be submerged but Minolta recommended that the 0 ring that keeps the camera back waterproof be replaced from time to time. It would be great to find some, or just 1. Or a broken camera that still has a good O ring.
