I don't like it. But that's just because of my anti-combustion bias :?
Objectively, it's a very well made cannon and my only criticism is that you left the handle unpainted.

It looks nice!
Finally another non-USA cannon that uses european (or dutch) fittings!
I thought I was the only one with those kind of fittings :)

Paint the handle and the barrel :)

The fitting is home made, It was a capsule. have drill a big hole in it and and it permanently melted. The painted PVC was grey, olmost everything is grey here. I have taken blank for the rest because I that beautiful find. We do not have here also of that beautiful funnel pieces :( Only ugly with the breach for the barrel to the upper part.

Meanwhile I've modifeded the gun a little bit. The barrel was broken so I had to replace it with anotherone. I chose a smaller one, so it became more like a handheld. Here's the new picture:

you would rather tote around a pump or compressor? :snorting:

a small tank of propane is easier to carry and use.

A small tank of propane is heavier than a pump...
Pneumatics are stronger, but simple combustions are more portable(Simple combustions only need deoderant or something.)

home depot has weber 3613's for $10 with wires and spark "cage" (i use a couple machine screws)

they have them cheap on e-bay, $1.99 for qty of 1-5 and you get a better price on larger qtys (6-10 drops them to $1.59) shipping for 1st is $5, only $0.50 for each extra...
