Bill,
Here is a website that you may find interesting. Notice the author mentions the 2 gal. can but doesn't show a photograph. Perhaps you would consider sharing your execellent photo with that webpage. From the home page click on the "J" for jerry can!

I think I saw a report on jerry cans in Army Motor mag. not long ago but the author didn't mention the 2 gal. rectangular can.
