Help Me ID This Compressor!

[Bruce Amacker]

I'm helping a friend with this. I think it's a 3ph 10HP Quincy but I'm not sure. The only thing I'm sure of is that it is 3 phase. There are no tags at all on the motor or pump, and the tank tag will be worthless for the most part.

Any info?

Thanks!

Obviously it's a Holley!

Seriously, that's a damm nice compressor.

Proudly built in the U.S.A. by St. Louis Shipbuilding and Steel.

From the website: St. Louis Ship was located on the site at the foot of East Davis Street in the Carondelet section of St. Louis, where James B. Eads built the Union Navy's gunboats during the Civil War. It was called the Rohan Boat, Boiler & Tank Company when it was acquired by Herman Pott in 1933 and renamed St. Louis Shipbuilding & Steel Co. It closed in 1984.

They had a subsidiary called Federal Barge Lines, which built tugboats. Maybe that was on a tugboat at one time.

The pump is a Quincy 325

If you're sure that's a 10HP 3ph motor, then that's unlikely a Quincy 325 because it's typically driven by 3 or 5HP motor. However, from the photo, that looks exactly like a Quincy 325 pump ... lol ...

That motor looks like a vintage westinghouse

Relatively certain that's a 5HP motor, really small for a vintage 10HP.

X3 on Quincy 325

The data plate is on the compressor pump, painted over, on the bottom edge of the side access plate on the crankcase. You can barely see it in the pictures above.

If it has stamped numbers in it, it could read like this: "325 14"
with the first number being the pump model number, and the second number being the Record Of Change or ROC.
