Our very Rare Lead spray gun

I bought a bunch of stuff from the college city WWII air base. I found this metalizing gun? I think it used wire and sprayed hot metal? also picture of lead army men

 

the rig has outlets of gas and oxygen and compressed air. and the top had a set of gear driven feed rollers. I really don't know anything about its operation?

 

Earth week! yep Its time to pileup the last years old discarded tires. Sit around and drink beer and enjoy the tire kill bon fire!
