George, you mentioned that the Elrod rig looked like a Bandit. I did some searching on Bandit. Narrowed to Bandit I, but I didn't find any good pictures of machines with them, yet. Found one at a distance. You can see it's a box with a motor to the right mounted to the front of the head, but that's about all unfirtunately.
If you happen to run across one, could you let me know? Sure would appreciate it. Thanks for the reply by the way.
