Update:
With the thermostat at the 9 o'clock position, the unit did finally shut down with approx. temp readings at 23-25 degrees for the freezer area and 40 degrees in the cooler area. And with me playing around with the door open, the relays "chattered", compressor kicked on, relays stopped "chattering as the run relay engaged. Compressor temp was cooler since I could keep my hand atop which led me to believe the unit shut off some time ago and was getting close to restarting when I began checking/recording things at which time it restarted.
With all this said, I'll assume she's "good to go"!
Anything I should be wary of David...? I'm not going to use it daily but will run it from time to time throughout the rest of my years...
Many Thanks again for your time and input!
And lastly, at some point, I am considering you work on an early 1940's Mills refrigeration system. Would this be something we can talk about...?

Glad to see it going back together! The DR manual has some control switching setpoints called out so you can see what it is supposed to switch at. If you can't find the info, I can look it up but currently very busy at work.
As for the temperature of the compressor dome, these do run hot because they are high-side housing machines. It can continue to get hotter and hotter the longer it runs, if the ambient temp is high, and especially if the unit isn't on the cabinet. The evaporator has a high heat load which it never gets any relief from when the cabinet isn't containing the cooling around it. It's very hard on these to run them without a cabinet for long periods.
