I'm reminded of "rescuing" an AA truck from a barn in Amherst, NH. Bought the truck for $100, and it cost $150 to have a wrecker flatbed to haul it home.
The truck had originally been some sort of "box" truck. Once home, the metal box sheathing and wood frame were removed to get back to the basic chassis.
Double rear wheels (5 hole) upon which I discovered the subtle markings "R" and "L" holding the wheels in place.
While in the barn, the barn roof had rotted out, and the rain water continued downward and rotted out the fabric roof of the 28-29 squarecab.
The Owner at some time had removed the 3 speed transmission top - which was sitting on the seat springs, now collapsed after the leatherette covering had deteriorated. The rainwater had collected in the transmission, which while rusted, was still able to be "turned."
The truck had been a "useful" truck certainly up until possibly WWII - but had sat there since. It had signs of a previous rebuild and restoration to service (I've mentioned the "sistered" frame.)
Everything of that rebuild was done "right." I continue impressed - and wish I had kept more of that truck for myself.
