Did Mr. Shelby,Sr. ever visit The Banjo Car Corp?

We are looking for a bit of American History to see if Mr. Carroll Shelby, Sr. ever visited a shop in Mineral City Ohio back around 1962 to 1963. This would have been around the time of the "King Corba" (Cooper Corba) was introduce on the race curcuit and he may have had contact with the Banjo Corp that was building a GT Coupe called The Banjo.
Being new to the Shelby Forum I hope this is the place to start. We were told that his grand son (Randol Shelby) mite be able to help us find this info.
