Looking for a lighted sign canister

[pinballdude]

I'm trying to find a lighted sign can made by BENCO PLASTICS INC. (BPI) of Knoxville, TN. It does not have to be in working condition.
A similar one is on ebay with a Fanta face. I have an extra face and would like to get a fixture/canister for it. It's about 16x13 inches. Uses 2
floro. bulbs. I realize this is a long shot but thought i would ask.
The one on ebay...

Maybe a light table the women crafters use would work. Hobby Lobby etc...

I have one in the shop.  Its in a Dodger Soda brand.  Will have to check the dimensions but it looks similar.
