A used Model K that has wear,but not abuse.Top has one noticeable dent I've shown close up.
It should work once an air compressor is hooked up to it,but I haven't one to test.Comes with the original,very clean filter already installed that I hand washed myself.The entire unit was washed,polished and has no debris in it at all.
Very respectable clean & solid.
-$60.00
