Old Fireman's Funeral

I know little about this picture of a fireman’s funeral, that was sent in by a reader about ten years ago.
I am sure the driver of the engine was my father, who was a fireman during the Second World War, rising to station officer before injuring himself while using a hook ladder.
The ladder allowed them to climb tall buildings by sitting in a widow ledge, pulling the ladder up and using the hook to smash the widow on the next floor before climbing and repeating the operation.
I remember my father who died over 40 years ago saying they were told they could keep the old brass helmets when the new style was adopted but he didn't bother.
