Breech seal needed for old Vostok .177

[boonergooner]

Hi, does anyone know where I could purchase a breech seal for an old Vostok .177? It's markings include "Made in USSR" on the side of the breech and a back to front "N" then *-38 on the top of the piston chamber and what appeares to be a serial number "M46 740" on the other side of the breech.
Any advice would be appreciated. Cheers.

Does it still have a breech seal? And if so, is it leather or a synthetic o-ring?

If it's leather you can make one pretty easily, if it's an o-ring it's probably a standard size you can get at a car spares shop or find in a pack of assorted rings.

If you can measure the I.D. and O.D. and the depth of the groove it sits in, I can tell you what size 'O' ring you need (if an 'O' ring is suitable).
