Jim, I had forgotten you were one with swapped wiring. As you mentioned, not a big deal.

plus my Torsion Level system had the 1956 Compensator switch
The torsion level switch is also a mixed bag. The stock 56 switch is identical to the 55s electrically. The difference is in the wire terminals -- 55 had 3 screw terminals exposed to the elements and 56 has bullet type connectors enclosed under a weatherproof cover plus two additional tie points for the different type 56 limit switches. The 56 switch was substituted for 55 switches if one needed replacement after the 55 stock ran out. A short piece of wire loom was offered so as to be spliced onto the original 55 loom because of the different terminals.
The issue comes if the switch has been replaced with one of the reworked switches sold by one of the regions. The bimetal time delay circuit on those has been replaced by a solid state timer. If the solid state components are polarity protected, no problem. If not, then smoke is let out. I haven't seen one of the replacements and don't know if it is protected or externally identifiable.
