I found out I had a wossner in my 501...only found out when i tried to fot the original/spec rings...wossner are slimmer rings. {less friction which is better in some ways, i suppose}
I got probs with it...except when i needed the rings quickly and they were the wrong ones...so had to send piston away to get rings for it!!!
