Unidentified trailer

[TadB]

So a buddy of mine called me yesterday, he had a trailer sitting on his head he wanted gone. He asked if I would come take a look and see if it was something I would want. Long story short, I ended up with it. I have no clue what it is. I have 2 m447 trailers, it has some of the same characteristics just alot newer. The sides runout hydraulically like slide on a camper. Just trying to figure out what it is so I can find the manuals hopefully

The Data Plate for this trailer should be on the outside of the trailer. I have seen this trailer when I was in a Missile Maintenance Company. It was used for ADA, Vulcan/Chaparral "Black Box" Repair, and also our TMDE repair Section. Its fairly old.
