The last oddity/difference in COUNTERS installation between the COIL, Aerial Tuning and the Sender has to do with the little six-sided metal plate and Locking Nut Posts fitted to each item.
The first photo shows these two items on the front panel of the Coil, Aerial Tuning. The plate measures 0.067 inches thick and the base of the Locking Nut Post 0.055 inches thick. The second photo is of the same two items found on the front panel of the Sender. Here, the plate measures 0.125 inches thick and the base of the Locking Pin Post 0.125 as well. The second mystery. Why wouldn’t Marconi have used the same sized plates and pins for both pieces of equipment? David
