Som, I have owned a couple of these. I don't worry about getting the seal numbers I just measure them with a vernier and source the sizes online. They are easy to fix until you start stripping the back end which is a fragile alloy casting. I had one that was cracked in the pressure chamber but was able to fix it inside with plastic metal. The main pump head seal is an O ring which I found easily, this is the main one that wears. They should only be lubed with a very tiny amount when assembling and no more after that.The dry fire and cocking sometimes fails due to side play in the lever, I just used a thin washer under the E clip to pack it out. They are lovely pistols and push out more power than some other SSP competitors.
Regards, Baz
