I took a chance on this compressor today at the local Restore for $7. The motor works and the pulley moves freely on the pump. So far, I've been unable to find a tag or label on the pump, only a Packard Electric Corporation motor tag on the 1/3 HP motor. The motor looks like its missing the band around it. I scoured the internet but could not locate an exact match though I did find matching pulleys on an old Ingersoll-Rand and Speedaire pumps similar in size to this one. The only other clue is that it appears to be painted dark green. This is all mounted to a piece of 3/8" steel plate. I thought I'd throw this up here and see if anyone might be able to identify it.
