Congrats on making Supremus, Spareribs! I was hoping you'd make it!
I love the old phones, too. I have fewer than headphones (

) but will pick up more when I have the room. They're dead simple to work on, built like tanks and the handsets are way better than any modern phone.
A couple favorites are the North Electric "Pyramid" and the Stromberg-Carlson 1243.
Cheers!
