$12,345 · VINTAGE 1960s-70s CAR PHONE

This is probably a long shot but here goes. I am looking for a vintage car phone similar to the ones in the photos provided. My research indicates these early phones were of the dial type. Phone does not have to be functional but must be in presentable condition. I intend putting it on display in my 1968 Cadillac (nicknamed The Mafia Staff Car). Any leads would also be much appreciated.
