I was able to pick one of these up (more than what i think it's worth?). It was definitely missing the puncture knob, clip spring, clip lock Buna O-ring 14-70, and the clip spring cap, but either way I liked the idea of getting to look at its internals and how it all worked in terms of pistols. Moving on, I couldn't find any info on it, but I'm guessing modders already know about it. I didn't know that the clip on the marker can actually be removed(see pic). I've just never found a forum that said it was possible. Just needed to take out a screw that sits in the back of the clip. once that's removed, gonna need a mallet to take it out of the "trail" that the clip is pressed into.
