I am looking for information, particularly information on the dimensions (height, width) of the Hall Signal Disc (Banjo) (see link below) thank you http://www.rrsignalpix.com/hall_disc_signals.html
I think Model Railroader ran an article on building these way back in the day- 50's or 60's. I remember seeing it in my collection of old magazines but not sure of the issue. Definitely cool looking signals and not something you'll see on everyone else's layout.
