With a little re-design it could easily be break action like the original.

Almost 200FPS is pretty good. Definitely more practical (or rather less impractical) than before. It would be fun playing with one of these. Or with two of them playing 1 on 1.

But thats not what you asked for. You wanted one, the only one being the impractical test version i cut.

Haven't weighed my Goblin cartridges, but I have gotten pretty good results by filling them with an inverted 3.5oz tank. This yield just over 200 fps, the highest recorded shot with my Deuce being 210 fps.

I even managed to hit someone last month, I think.
He was trying to bunker me and I leaned out a window, opening up with my T8.1 in one hand and both barrels of my Deuce in the other. Not sure which gun caught him in the finger, but at least something hit him.

I've got 3 cartridges and 2 of them were leaking through the fill apertures.
I ended up fixing this by replacing the spring in one with a stronger spring from a shraeder valve out of the valvecore from a valvestem in a tire.
Both of these springs then needed to be shimmed with a bit of toothpick before the valves would close and not vent after filling.

Which one? Not the vent in the fill nipples, is it?

Remove the spring that holds the main dump valve shut. I found that without the spring, the valve opened far more quickly, and velocity was much easier to obtain.

Leave/increase the tension on the fill valve spring, as that is an issue for leaking. Of course, you can shim some of the seals with a little teflon tape to make them hold a little better, also.

I don't think my cartridges even came with this second spring you're describing.
Perhaps the previous owner removed them all.

What's the best method you've found for increasing the fill valve spring tension?
My shraeder core springs and toothpick nubs are barely adequate.

I simply stretched the spring a bit.

Your's use schrader cores? Mine look like the fill nipple on a butane lighter.

Dukie if you could get this actually working, make it like a flashlight gun and I will holster it under a kilt.

Zip guns with Goblin shells... That might have a cool factor

I tried stretching a spring at first, but I ruined it to the point that I can't get the stem to screw back together with it in.

shraeder cores were just the first thing I found with a comparable spring; I had been looking for suitable springs for a while and happened to see some broken ones lying on the ground when I bought some used tires.
Getting the springs out of the cores is a bit of a trick, though, and required multiple channel locks and some careful cutting with the dremel.
Brass valves are easier to dissect than steel ones; that much I've learned.

Lol!

I honestly have no good solution for the spring issue... Wind your own?
