Quick trailer identification needed!!

Ok. I don't know squat about old military trailers, but this 'utility trailer' has a military appearance to me, particularly the tail gate area. Is this a home build or an old military trailer? It's listed for $100, so I'm really hoping it's military.........I'm meeting the guy at noon, so I need to know quick. Thanks!

 

Might be a second version Converto dump trailer. Make sure it has a suspension because the first did not. Pintle was replaced. I'm just guessing from what I can see.

 

Hard to tell from the pics, but the front shot looks like a 50s pickup bed

 

You guys must have better eyesight than me. I can't tell what the heck it is from the photos. Please try to post some without the tarp, shot from different angles, with some close ups.

 

X2 from the pics it looks like a green trailer but I cannot see any details.

 

Well I went to look at this earlier this week. Of coarse I forgot my camera....from what I saw, the box is definitly from a military trailer. It had the 45 degree 'ledge' along the top of the box. I don't ever think I've seen this on a truck bed. The problem was the liftgate was from something else (countours didn't match) and it was mounted on a round tube frame (everything I've seen has a square frame). The leafs were mounted to the box via a 2x12. It wasn't in horrible shape, but from what I've seen, I can pick up a decent bantaam for $500-$600 in good-great shape. I would have to sink hours and hours and dollars and dollars into this thing.....
