In some emails with a former AEI employee today, I was able to confirm
for certain that the 1950 photo of the Summerside switch was indeed
Siemens/AEI equipment. Type 51 selectors, etc.
How this came up is he contacted me, and wondered if I would like a
Type 51 for the museum. In later emails, he told me both the
Summerside and the early Charlottetown switch was AEI...
It has taken me a long time, as no-one on the Island remembered who
made it - finally I have proof!
Out of the blue!
