MilkeeP - I’ve had this thing for years, what is it?

Most round here most had a 12x18" box. Aluminum outside.

Most got one quart or pint twice a week around here.

We were the last family in town getting delivery when it ended in the '70s.

At that time we got two 10 quart containers of whole and a half gallon of skim every Monday and Thursday.

The front door was never locked and the delivery man just walked in and put it in the fridge.
