Many thanks to Hendeyman! He provided me with this via PM:
"Greeting Nic:
Hendey lathe No. 36776, a 16 x 30, 18 speed Geared Head model, was ordered on November 14, 1945 and was schedules for completion
during July 1946. The long production delay was caused by the end of WW2, There was no production during October and November 1945
and during January and February 1946. The electric motor was a Frame 324, 7-1/2HP, 1200RPM, 440Volts, 60Cycles, 3PH. The Clutch Pulley
speed was 575RPM. The original owner was the Socony-Vacuum Oil Company, no city or state was listed. There are still a few Patterns, Cast-
ings and Repair Parts left in inventory for this lathe. All of the original drawings are still in the files, so part can be made if required. If I can be
of further help, let me know.
Best regards,
James F. McDerment (Hendeyman)"
SO after a short google this is the company that became Mobil and of course now is ExxonMobil, wonder what they used it for!
