Before my parents moved out of their house this past fall, Dad had a green wall phone like that in the garage. It worked just fine, ringer and all. He bought it at a church rummage sale for 75 cents. I have no idea whether the clean-out crew took it or tossed it or just left it behind. That was a very common color so it shouldn't be too hard to find a handset and cord. I used to have a black repro phone just like that. It was branded "Pac*Tel", which I think was Pacific Telephone, one of the "baby bells" created after the original AT&T split up in the early '80s. They used to sell those Pac*Tel phones at Circuit City for around $15 or $20. Those phones wouldn't work for me today, though. I haven't had a land line in almost 15 years.
