Compressor pump id help

[fishing4fun2]

Can anyone ID this pump?
Don't go by the green color, the original color was blue.
The pulley is 16&3/4"
No tags no stickers just casting numbers covered in thick paint.
I was leaning towards LeRoi or Ingersoll Rand but I have not seen one the same after looking at several.
2 stage maybe 5HP?

This is a Schulz pump, made in Brazil. I believe Champion used to use these on some of their stuff for awhile. Also sold under the Ranger name brand, at least in Canada.

Thanks, Mac, I couldn't id the pump or even find anything looking the same.
Now I got a start with your information, I want to get this up and running soon.
