Here's my helmet as of today, with mods, cushioning, ventilation, and more accurate (of course, this will be a custom-scheme helmet, mix in between ESB and ROTJ, without compromising the ROTJ look too much. (Shadows of the Empire, perhaps).
Cushion, 9V battery connector and on/off switch,
Cushioning and CPU fan installed,
Ventilation screen in the rear (inside),
from the outside,
Green left side painted silver, and "kill marks" repaint,
RF repaint and REAL weathered, plus RF "screen",
Front view in the sun,
and forehead "arrows" detail painted.
Hope you guys like my progress (just a little), and I'm still missing just a few little details.
