Can anyone ID this small DeVilbiss diaphragm compr

I hope I have my terminology correct there. Unfortunately someone removed the tag from this little pump so I cannot tell what it's purpose was. Does a fine job on tires. DeVilbiss can't help at all. Would be very grateful for any info. Thank you.

Thank you for those comments. As you gentlemen said, it must be old, not just from the style, but the quality. I would like to find out what kind of spray equipment would work with it. I understand motors can be dated from the code letters so here is a photo of the engine plate if it helps? Thanks again.

Bleeder-type spray guns and similar design airbrushes were used with these. Add a small tank and an adjustable popoff valve and you can use better types.

I grew up in my Dads shop from a toddler on, and have fond memories of some of the tools and equipment that he had.

He had one of these compressors and two others, larger and HUGE. When I was little the one like this one was already old and well used and that was over 35 years ago. According to my Mom's recollection he bought it used in 1957.

It is definitely a diaphram type, because I remember it torn apart once for a rebuild. He used it regularly with a small pressure cup spray gun and also for air brushing. I thought of that old De Velbiss recently and wished I had it still just because it stands out so vividly in my memories. That one was sold at auction after my Dad's death in 1976.
