What type of call phone used by Thorndyke?
During the movie, Thorndyke made calls from his car phone. Cell phones are so commonplace today that this didn't seem so unusual...until one realizes the film was made in 1968. Can anyone describe what kind of phone this was?
I'm aware that telephones in cars had been in use for decades before 1960s, but can't find anything that explains how they worked--especially, how did the radio car phone make a connection to the land-line telephone system? Did a caller always have to go through a radio operator to make a call?
