Ok, it's worse than I thought. I took the gearbox apart and I dare say there is not one swapable part in it! The cylinder, cylinder head, nozzle & tappet plate are all molded as one piece! The piston is about 25% longer than a regular one and is about 25% smaller around. The gears are all different than standard, the anti-reversal latch is on the opposite side of the gear box. Even the spring guide is a different size at the base, the standard being smaller so it doesn't fit properly. I'll post some pics later, after I calm down a bit more.
Too bad there's so much plastic. With a bit more metal, it's be a decent boat anchor.
Beware DO NOT BUY A FIREPOWER GUN!!! This thing is worth $100, absolute tops.
