I've always wanted 1/6 scale TOS Trek figures but never got really motivated to do any until nanjin over on Sideshow Freaks forums was making TOS Kirk, Spock and McCoy to sell in limited quantities. I was very impressed with the figures but never would be able to afford them so decided to make my own.
Spock - The body is a Soldier Story, the hands are TTL v3 and the head I got from Lonnie The frontline custom head he doesn't have the Spock head on his website I got mine from ebay, but if you email I think he should be able to let you know where to get them.
The pants are from the 12" TOS Playmates figures I just cut them off the outfit, the top is from D-Art Studios http://www.d-artstudios.com/index.htm. I couldn't find any swirly embroidery so I cut up some old 1/6 straps I had in my bits box and painted them gold.
The science emblem on his chest was drawn by hand and then hand painted as my printer decided to give in and then it was glued inplace. The boots, tricorder, phaser and Vulcan saluting hand are from the old Spock AMT model, the tricorder has had a leather strap added.
Base - is from an old Indy figure I had I'm just using it as a generic base till I build Kirk and then I will be making a dio for them both.
