When my Mom passed away I had to empty out her house and one of the things she had were 2 phones like this one.
I held on to them but eventually sold them a few years ago. Now I want them back. These things were so cool inside. Really super-basic electronics. Some wire, a big electro-mechanical dial, and of course, a real bell that rang because an electromagnet drove a relay that smacked a little hammer against it. So cool...
