Surfaces include: bracket - facemask mount, button, front base, helmet inside, helmet outer, helmet stripe, pads, rear base & screw.
To accommodate many configurations, twelve different facemask models are available for sale individually on Turbo Squid. This model is also available on Turbo Squid with a facemask. The file is named fbh-opo.lwo. This file also displays more images of the helmet.
I plan to post the helmet with all facemasks as a set.
