Tool ID

[Levaughn]

Hello all. Could someone explain to me what this tool is and what it's used for. I found these among some tools and have no idea what it is. Is it missing some other parts? Thanks in advance.

It looks like an air gun

Yes, looks like some sort of specialized compressed gasses gun. I'm not sure what profession would use it tho.

Compressed air wash gun I think. A detergent solution is connected to the small ****** and compressed air siphons it out, often called engine cleaning wands I believe.

Kind of looks like a siphon spray blow gun to me. Looks like there is a a hose barb on it.
