Is this an ex military wrecker body on the rear of this truck?
Holmes?

Looks like a Holmes rig but the body is not that found on CMPs.

Holmes wrecker gear on a home made rear body by the looks of it. Note the twin spare wheel mounts on the top :D

969 Diamond T rig perhaps

The Holmes rig appears to be the same as used on the WW2 Diamond T Wrecker and is very likely from one of those vehicles.
The 4 ton 6x6 Diamond T was too slow and too thirsty for the tow truck guys and the rigs were often put on more modern, faster trucks.
