Two types known, the "DA" or "Double Air" and the "PA" or "Pump Action" (a.k.a. FX Exterminator). Lots of air (500cc minimum), and the same biathlon style sidelever action as the Cutlas. Also known as Logun Gladi8tor.
Does anyone have the measurements for the transfer holes in the gladiator/verminator variable power wheel? I'm sure i've seen the somewhere but now can't find them.
