Vintage Compressor Identification?

[Grzldvt]

I own an auto detailing shop, and while we are brick and mortar, we do have an occasion to be mobile and could use a small compressor. My neighbor had this compressor and gave it to me. The tank has a rust hole in it at the very bottom. This is the only thing I have to identify it. Any clue?
I want to replace the tank. I have no love for this one, so if the tank is hard to come by, it will find it's way to tool graveyard.

The faded remnants of the logo on the left side of the sticker on the tank looks like Montgomery Wards to me.

It appears to be a Montgomery Ward Compressor. Based on what Stuart said I did a little searching and found a compressor, very similar with the same logo. Based on that research, I think one is destined for the graveyard, as it seems tanks for this vintage are not available. I am not willing to buy a used tank due to safety reasons and new ones that much seem to be difficult to find.. I don't need this thing blowing and hurting someone. So off to the graveyard it goes.
Thanks for the help.
