Anyway back to the attention on this odd compressor.
I have photo of thing:

Air compressor was cobbled together decades ago using old freon
compressor. Rather poorly I add.
Now I'm rebuilding this compressor because of head gasket blew
I have tried two other newsgroups for HVAC and other one
rec.crafts.metalworking with little success.
Thanks & cheers,

My thinking, is that unless you can come up with a data plate from the unit,
you are gong to end up having to cobble together what you need to fix it,
yourself. Cobbled unit, more cobble, right? g
Or bite the bullet, and go get a small oilless compressor, at a flea market
or such, and pay 50 to 100 bucks to replace it.
On the subject of the lengths we must sometimes go to, to keep old "stuff"
running, I have a story.
I have a 194? (2, I think) Gibson tractor. It looks to most people like it
is home made. The trans-axle looks like the rear end came from an old
pickup, but it is their own casting. I had something go wrong (input
bearing failed) in the transmission, and broke 2 1/2 teeth off the sliding
(spider or shuttle) gear. My choices were to try to find a gear from
another junker of the same vintage, throw the whole tractor away, or find a
way to fix it myself. I could not find a donor for the gear, and did not
want to toss the tractor, so I made up my mind that I would do whatever I
needed to do, to fix it myself.
I used a wire welder, and welded, and welded and ground and welded to make
sure there were no porous areas, until I had built up the gear in the area
of the broken teeth with solid metal, to the full outside diameter of the
missing teeth. About 3 hours, as I recall. I then sat down and made a
cardboard template from the other side of the gear, and ground and ground
out the built up weld, using a die grinder with a cutoff blade, until the
teeth re-appeared. I used the mating gear to keep checking my progress, to
get the mesh just right, by eye. Oh, this was a helical cut gear, by the
way, and done with a hand held tool, and hand held workpiece. It took about
3 1/2 hours as I recall.
It was not perfect, but it was serviceable. The over design factor of the
gear was probably 10 times the stress the relatively small engine would ever
stress the part. I did not heat treat it, other than normalize it, then do
a heat up to red, and a quick oil quench.
So, how set are you on making this old unit run again? g
