I dropped Bob Brechin a line asking if they rang any bells, the reply back was;
"the figures are some of the many that were developed and discarded. I distinctly remember the guy with the beard. I think he was part of some scientific team. We made up and did paint jobs on loads of figures until we hardened down on the five teams including the "baddies"."
Brilliant that you're still hard at work chasing leads on all this Indy.
Many thanks and keep up the good work!
