If it’s a new to you job on your route, have your salesman push it onto the building owners. After all, it’s their equipment. Sounds tough, but 1964? C’mon.
If your office can’t find prints or the building maintenance doesn’t have possession, go to the next step and divorce yourself from the issue.
Without drawings, well, your SOL right? Even the seasoned TS is helpless without drawings on vintage equipment.
You can service anything, but you can’t fix everything.
Is it a complete dispatch failure or just floor 6 for one or the other car? Shutting off one car frees the other to dispatch, or no? Does this duplex have fire recall Ph.1 only?
Nothing written on any controller cabinet door? Or a wall? Some clue somewhere?
If not, there aren’t too many choices left for your customers 60 year old equipment except MOD with plenty of suffering in the meantime if the building is getting busy. You posted a few days ago for anyone having prints…crickets so far on that one.
