From your farm truck photo those are WORKING guns, tools in the truest sense of the word. Most airgunners baby their PCPs and consider them objects of endearment, to be enjoyed, coddled, and then spotshined back to perfection prior to gently placing them in their dedicated safe place.
But not Dillon.
I've spent some time in farm trucks and they're tough place for a PCP to live, dirt and dust and heat and cold and bouncing around. Windows get left open all the time, day or night, rain or shine. I can only remember my uncle cleaning any of his farm trucks one time in the last 30 years, at least that I witnessed. And that "cleaning" was to blow the dust out with an air wand on a compressor, and only cuz he happened to already have the wand out to blow out the filter on a tractor. Can't believe the cloud of dust that came rolling out of that truck.
I love it. Really gives a sense of the toughness of the tools you've chosen for the pesting task. Almost on the level of Dana's torture test, but of course not quite.
Thanks for sharing.
