How did you come by this fact Tony?
Not saying your wrong, just curious.
Although, I'm nearly 100% certain that that complete set of first 100 TMG's were all Demos.
They were all laid out on a table or bed and I remember the change in colour as the Demos went from white with a red 'A' to green with a white 'A'.
Or did I imagine it? Doo do doo do, doo do doo do. :o)
