Gast 05230-V4F-G582DX vacuum pump, with G582EDX 1/3HP motor. From a closing industrial facility.
Tested October 2023 and working, but note that they are in rather rough shape. One powers on, but doesn't power off when switched off: you need to pull the power cord for it to turn off.
The one gauge also broke off at the stem as pictured. You can take the pipe piece still in there off, but it will be somewhat challenging.
