No doubt about the age--- marked 1970.  Very clean-- never been used.  I have a few of these and they would make a great wall display as some twee shops are doing now.   21 inches long,14 inches wide and 10 inches deep.   Very strong -they have internal corner posts. .   No worm.     For collection only from 5 miles West of York,    CASH ON COLLECTION PLEASE then if you see the item and change your mind( you won't !!)-- you can just walk away and spend the rest of the day in York-- the top place to live according to the Sunday Times.
