I have 1940 Monarch lathe with original motor. This is a dual voltage motor with 9 leads.
Sure look like its connected for low voltage to me. Threw me for a loop for a minute, since this isn't the "normal" 9-wire dual-voltage configuration. The normal is a wye connected motor, and the low voltage has each incoming line going to two wires, with the remaining three tied only to each other.
This one has line going to three terminals each. I scratched my head for a while and sketched on a napkin, and realized that this motor is delta connected. But the connections all make sense.
What are you trying to do? Do you want to run it on low voltage or high?
Regarding the cabinet, never trust a label that says "wired for xxx volts". When I bought my bridgeport, the motor said "wired for 480V", but the twist-lock plug was for 240. I got suspicious and opened up the junction box, and sure enough, someone had reconnected it for 240V. There was also a small transformer to power the DRO and power feed, and checking its primary wiring confirmed that it too was wired for 240V.
I suggest checking everything you can in the control cabinet for clues. Contactor coil labels, if the contactors run directly from the line. Control transformer primary taps and wiring. There are probably other clues as well.
