Mac, what is the TM?
This use of the UK mold phrase is a misnomer because it is hypothetical. So to say the TM is a first gen casting from the UK mold is not true. There would be some ancestor of the TM from a hypothetical mold taken off the original ANH helmet in the UK around the time of the ANH production. That ancestor would have served as a basis for the ESB helmets, and one of which was modified, then a mold made of that, and that gave us the TM mask.
