Drawings are what the machinists and engineers use to make an item. A drawing typically will give dimensions and tolerances they need to be within. These appear to have the numbers removed from them... I assume to keep another machinist from using their data for making their own.

Thank you. I did not spot the numbers not being present. The thing regarding drawings though... The general purpuse is known to me.
These days though, nobody does hand drawn plans anymore, everything is CAD. Thats why I asked what the purpose of these specific drawings are. And to be honest, I hope for them to be included with the ears.
John though... I think with the box we have officially passed the point of legend status...
New helmet has landed in the UK and is out for delivery. This helmet was cast in TC 1630 with fiberglass in June of 2020 and has the following measurements:
Length: 10 4/16" (-2/16" or -3mm from the ESB Hero)
Width: 9 3/4" (-1/16" or -1.5mm from the ESB Hero)
This helmet has significantly less shrinkage than the first helmet that was sent to Elstree, which was cast in gelcoat resin with fiberglass.
