<div align="center">MARBLE CANNON

Provided By - Melkor

Yet another marble gun, nothing too special or unique, but in my opinion it's a good, cool-looking gun. This is an inline pneumatic. The 2"x12" sch40 PVC chamber is used as a stock, and the 1" modified sprinkler valve is connected to a blowgun which serves as a trigger and gives it a rifle-like feel. The barrel is 1/2" sch40 PVC. A 0-160 PSI pressure gauge and a schrader valve are tapped into the 2" coupler. A red-dot scope which I bought off eBay is mounted on the valve. When using similar marbles and a constant pressure, this baby can get pretty accurate... ;-) A rough calculation with GGDT shows that this gun fires at about 600 feet per second with 120 PSI.

Or a pressure washer, but the size of the outlet and the piece of hose to atach it make me think garden hose.

I have a handle very similar to this one. I got it at a local hardware store called Harbor frieght. They dont really have brand named stuf they make their own. What it really is made for is a pump for a tire. mines i little different but to me it looks really close here is a pic

it looks close, but the one you have may not accept air pressure throught the hose (though it should) try blowing into the hole the hose was in and see if it holds pressure or if it leaks through the bottom hole.

I have something similar to that called a DG-10.

I even filed the top into a sight grove.

I didn't know it worked through the top too, I thought they only worked through the bottom, guess I was wrong.
