MARK 3 Bomb trailer help?

[law]

Late year I picked up this U.S. Navy Bomb Trailer, Mark 3. I am finally going to start working on it, but have found zero info on the Mark 3. I have found documents, photos and info on the Mark 3 MOD 1 and MOD 2, but nothing for what I will call the “MOD 0”. I think I can safely assume that the fenders and deck were bubba added to this trailer post war, so I feel safe removing them, but would love to get some info, photos and documentation on the ordinal Mark 3 before going any further. Any and all help is appreciated.

Hello!
I hope these may be of some help. They're some of the original drawings for the Mark III. I haven't had a chance to go through them all yet, but when I do I will make sure to get record of all of them.
