Help Identifying an air compressor

I got this air compressor when my wife's grandfather passed away. I am trying to identify the model of the compressor itself. Based on other threads and resources from other forums, it seems to be narrowing down to Quincy, E.L. Smith, or Sanborn. I have no idea however and none of the images of the various models from each maker seems to perfectly fit. The closest I have seen was on this thread: https://www.practicalmachinist.com/...l-smith-portable-20-gallon-compressor.277610/

Unfortunately, there is no longer a manufacturer's I.D. plate on the compressor and I have no idea how long it has been missing. It was not on the machine when I found it. The only info I have found on the machine itself, it the number 104 on the cylinder case (stack, tower, thing? Not sure of the correct terminology).

I tested the machine for about 15 seconds to see if it would actually build any pressure, and it did, at least to about 20 psi. I didn't go any further.

I would like to attempt to restore this thing, maybe as a present to my father-in-law, who used it to paint cars back in the 70-80's.


Other relevant information, maybe:
Original owner was an electrician and seems to have made several modifications to the system.
We also got a 1962 Delta-Rockwell band saw (model 28-100) at the same time as the compressor, so it may be from around the same time

If it's the same as the one in the picture, it is an E.L Smith compressor. Several companies used this unit for their small compressors, so it might have actually been branded as something else, Sanborn being one of those companies. I have also seen it on an IR and Wayne.

I am not sure why, but the pictures I had attached to the original post didn't go through. Here are pictures of the set-up and compressor:
I was also going with E.L. Smith. Unfortunately I have not been able to find much on them, but I will keep searching!
