In October 2024, I had the opportunity to visit The Telephone Museum in Ellsworth, Maine. This museum had so much to see! It features many different kinds of telephones, manual cordboards, several Step by Step switches, several All-Relay switches – and finally an entire #3 crossbar switch and a partial #5 crossbar switch. This is a place that a telephone enthusiast must visit at least once in their life. There is a long write-up on my visit, plenty of photos, and also plenty of videos!
