After selling mine years ago and getting bitten by the Crosman bug again, I ordered one from Poland. It's the new shape but with brown grips and fore end, as well as being full power.

I'm surprised they use any kind of bleed hole or valve mods, it used to just be a reduction in size to the transfer port (sits between the breech and barrel. I bought a couple of brass/Viton ones from and have already fitted one to my 2240. Dead easy to fit, and compatible with Crosman steel breeches.
