Hi Bill, does OS still make replacement rings for the old engines? The one I need is for a 40 SR (non-dykes).

Please let me know if they are available from OS or if you know of a 3rd party mfg.

Thanks

We're sorry, but O.S. no longer makes piston rings to fit the old .40 FSR engine. Here's someone who does make piston rings, though. You can contact him for prices/ordering information.

Please contact Frank Bowman. He manufactures repro and current piston rings for our modeling needs. He can make standard and Dykes type rings. If he doesn't have the ring you need in stock, you send the piston and cylinder and he will make it then. prices are $7.50 up to $9.50. His work is of the finest quality.
