I spotted this in a nearby church. I hadn’t seen one of these for a while. In fact I thought they’d disappeared entirely and that when you heard the sound of church bells (which you don’t hear as much in Putnam Valley, NY as you did in Sandbach, UK where I grew up) it was piped. Just press a button and the sound of bells was played through a speaker on the roof. I resisted the temptation to pull it to see what would happen.
