Seeking a prior generation pressurized sprayer gun/system marketed by CorrosionX.

Their application systems come in different sizes, but the guns are common to all. Haven't had any luck finding any NOS (prior to a design change) in their distribution chain - so I thought I'd put out the word here on BITOG.

Thanks in advance, Gents.
