So funny to see those Indetel phones (lower left of first image) . I saw one on ebay and could not belive ITT sold them , It had the own a phone sticker on bottom, and it had the racing sripes like the one in the image .
I see a lot of those in Mexico , where I now live They are a dime a dozen. They are what Telmex used when they got away from the Ericcsson sets
They made push button models that were pulse dial push button as Telmex took for ever to move to DTMF . In fact I have one here and waiting on some Stromberg Carlson DTMF pads that I think I can even use the existing white keypad on. Posting a thread about this elsewhere.
Got my first old phone at about 7 years old.
