Marston.
Here is my 56
Not to happy about using bell wire. Especially on the lever. I'll change that to strained .. like Packard had.
What it is..no ic..(555) .timer. 2 timing circuits 1 for up.... 1 for down. Timing done by resistor capacitor..
Don't know why they used a signal diodes on mine..that are only good for about an amp.
Used them on my train layout in 80s..and would fry them..
