any trailers with square tubs?

I found a trailer near me. I haven't stopped to look at it (it's not officially for sale), but I got a good look at it today from the road. I originally thought it was a Bantam because it has round fenders, however, after looking at it a little better today, I noticed that the tub appears to be square. It doesn't have the top part of the tub that angles outward like the M416, M100, MTB, etc. have. Were there any 1/4 ton trailers that had square tubs? I'm thinking maybe it is just a home made trailer.

 

Please post a photo or two. There was a company in Fresno CA (now out of business) that manufactured a trailer with an almost square tub, known as a "Mule," but it is impossible to even guess at what you saw without a photo.

 

Sorry, I didn't get any pics, but after further investigation I'm fairly certain it's a home made trailer.
