Anyone know the brand name of this air compressor

[winners58]

My Dad built a gold dredge from used parts around 1969 and it had this type of air compressor on it.
I cant remember the name, I'm sure his was older than this one and mounted different but it had the radial fins like this.

Don't know about the compressor but the couple jet is the selling point.
