This is Aurora /Polar Lights' "General Ursus" from their Planet of the Apes series of kits. I built it straight out of the box.
At Wonderfest a few years ago, my friend Bryan was selling this kit for just $5, but no one would buy it. When I asked why no one wanted it, he offered to give it to me for free, on the condition that I actually build it.
Well, after a few years, nearly a whole pack of Miliput and a lot of cursing, here it is.
I tried to airbrush it completely freehand, but wound up having to use a mask on the bandoleer/cartridge belt and the boots. After that, I painted the details like eyes and buttons w/ a # 3 brush. Sounds a lot easier than it really was...
Bryan and I are still friends, and I've completely forgiven him. Totally.
BTW, if anyone knows of a really awful figure kit I could give as a gift, I'd be grateful for the heads up.
