Mystery spray gun

[OldnSlo]

Why on my daily pedal bike ride, I acquire many roadside trinkets. This had been sitting on my workbench for a few months now, and its time to sell it or bin it. I've straightened the spray handle.

It sprays some blue fluid, handles a high volume (and pressure) of air. Note the air fitting size in relationship to my pinkie. I was unable to find anything via the part number on the handle.

What did I spray?

No clue but first guess would be high volume gun for a back of truck pump used for insecticides, fertilizers, seed or maybe asphalt sealants.

Blue fluid makes me think spray indicator mixed with some herbicide as well.

It looks like a Hudson gun.

I can't imagine picking up a random spray gun with mystery blue fluid off the side of the road...

Hope you washed your hands!

Definitely a lawn sprayer

It's a spray gun primarily used for pest control, but some of us roof cleaners use these or similar on our rigs, since they're more robust than many similar options and can handle higher psi. Also used by lawn guys.

That nailed it. Thanks team! I'll list it for parts locally since I cant test it.

Much appreciated.
