What do you know about Curtis compressors?

[Jbullfrog]

I had a buddy load my new compressor for me. Now, I just have to get moved in to the new shop and get it wired. The date on the tank tag is 1948. It has a patent tag on the pump, but I couldn't view the images of the patent. I looked at the FS Curtis site, and the current compressor pumps look pretty much the same. What does anyone know about these? I am wondering what the CFM is also. thanks,

Nobody here knows anything about these?

I emailed Curtis, maybe they'll reply.

I emailed them too and got a response of "no information available, Regards."
