DANTES, I am at a loss to help you. Hopefully someone else will chime in. I will continue to look.
Do you have a city near you with a museum that you can call/ask them for someone to do a hands-on inspection n evaluation? (Are you in Georgia - it seems you listed Georgia somewhere in the thread.)

at the redneck games in Dublin, Georgia!!
