Large Air Compressor Identification Help Needed

[Mustangkr500]

I really need help identifying who made this compressor.
It appears to be well built but neglected so needs new rod bearings
Here is what I know:
5HP Doerr Motor 1740 rpm
2 Stage
Block has a serial number (in picture) 088311360
Pump looks to have originally been blue?
Pistons have stamps that say ind. bras. which i read means it was made in brazil.
The Ind. Bra. is on the metal air box it says "Mann" Filteros "Ind Bras"
Will update with more info as I find it.

When I looked at the pictures, I thought Schulz... When you said Brazil on the piston then I *really* thought Schulz... Might be a good starting point?

Thank you so much for the info, I will look into that.
Do you know anything else about Shulz? Are they still
around, parts, owned by another company, history?

Thanks!!

I think you are right on the money, I look at the shape of the block and the
head designs and they look the same on the current machines!! Shulz has got to be the brand!

Yes they are still around, just google them and you will find their website / contact info.
