Not the same subject but close. My uncle was in a truck during the mid fifties and knew that I had an interest in the FDNY.
He told me more than once that I should have been in the firehouse the other night. The bell was under the ladder, rung by a member riding the side. That particular tour they had two members, a chauffeur and a tillerman plus the officer. He laughed that they needed someone to ring the bell, but this was before overtime and minimum manning. I remember that when I eventually went on the job, the bell and the correct ringing of it was very important to certain officers.
