Nope...have no idea how anyone else could either...
I have tried several times by phone and letter to get any records in the archives of Military Historical Archives and other sources to see what, if any, information we could learn from any source that still has info.
To date, not one document has come to light from any government source about these trucks.
If someone has found such documents, I for one would be very interested in it/them.
Lord send your Holy Ghost into our hearts and make the desire of our hearts Your Will.
