Howdy Frank,
You have a parking meter question and I am currently working on shelves to hold a few of my meters.
That bracket is very interesting. I have never seen one like it with any of the meters I have. To make a guess I would say it goes inside the coin vault and is held down with the same bolt that tightens the mounting wedges. That would be my best guess.
Good luck and may God bless us all,
Mike
Thanks Mike. If I can figure it out too I will let you as well. Maybe its not for a Duncan which I have. I will be getting my first meter on Monday and maybe the part will be in there lol
PS Mike could you take a few pics of the inside of one of your Duncan 60 or 76 so I could have some reference of what the inside looks like and how does the nob come off and the coin door? have a great weekend
