FWB CO2 Seals - source?

Does anyone know a source for CO2 seals for the older Feinwerkbau CO2 pistols?

Mine is 1990 vintage, and suddenly will not hold pressure when I screw a cylinder onto the gun.  It appears the "white" seal under the firing valve may have some degradation.  It "pukes" gas out the crevices of the "receiver" (ie, not where the cylinder screws onto the gun, but from the pressurized interior of the gun).

Thanks everyone...

You might try asking on Target talk

They actually have good Customer service.

They might actually reveal the material and hardness of the O-ring for local purchase.

If you get dimensions of the O-ring check-out McMaster Carr, they have large selection of O-rings available.

Appreciated your suggestion, Dave.  I reviewed the exploded drawing of my gun (C20) on their website, and wrote Feinwerkbau directly.  Their sales person responded promptly to inform me they had the requested parts in stock, and with a list of US representatives to order through.  It was Pyramydair, Pilkington, Champions Choice, Oberle Enterprises, and Sport Shooting Depot.  I obtained the parts from Oberle's, who were very helpful, and replacing the suspected culprit seal fixed the problem.  Gun is operational again.

Thanks everyone who responded!  (Now if I could just re-learn how to shoot it...)
