Looking for information
 

I just bought a mini pickup. It is registered as a 1961. It was restored with a new body. The guy that built it had died and I am buying it from the family. There are many parts and two truck that were parted out to build the one I bought. One of the trucks that was striped has round tail lights and has a different looking over hang on the back of the cab. I am hoping to find information or get pointed in the right direction to learn about early mini's and specifically mini trucks. Any help is appreciated.
