That looks like the phone we had when I was a kid in the ‘60s. Do you remember the phones that were out for a while in the early ‘80s that had push buttons but still worked as rotary phones? You’d push 7, say, and it would make seven little clicks like rotary phones did. They didn’t work for any of the touch-tone things, either.
Yup, and on a phone “0” isn’t “0”, it’s “10”.
“Cobra” brand. Funny looking thing. There was a button on it so if you just set it down (or slid it into the wall bracket) it would hang up.
Anyway.... it has a switch on it so you can go from touch tone to pulse dialing if you happen to move to 1974.
