Donald, I'm interested to hear more about the Maas-Rowe controller. I presume something that plays a fixed peal on the chimes ?
I found another You-tube video where someone was describing a set of chimes, but it had a tube amplifier and a small manual keyboard. He didn't describe any sort of automatic player, and from the age of the system I would imagine it would have been semi-mechanical, like a player piano. How does the controller you are restoring operate ?
