I like the description or the basis of your system. All Lowther, all the way to fieldcoil. I believe that this is the work of a German outfit that recones, remagnetizes Lowthers as they hawk their wares and services in Ebay.
Can you describe how you run the systems. To me there seems to be at least 3 distinct systems, and at the very least 4 differents cabinets you their own Lowthers or 4 cabs and 1 set of fieldcoils?
Nice decor.
