What I am thinking might have been, is a pendulum or platform escapement slowly advancing a tuning condenser. PS. Even clockwork toy trains had the means to engage reverse when reaching the end of travel. I had a Regonda Symphony radiogram that did that, and was able to automatically stop on a station by monitoring the AGC voltage. That's very interesting. Did you have to wind up the clockwork, or was it electrically powered? |
