I did this one a few years ago. It's a wee bit bigger now but not quite as big as bullshooter's....yet
I prefer the bone look. A coat of nail polish for the gloss look. A jake beard fit better than a long one in the shell. I liked the idea of seeing the top of the shell instead of putting the beard in the usual way. I just cut out a slot and hot glued the beard in.
Once the leg is dried it's pretty easy to cut off the skin. Marrow in the center of the bone pushes right out or if it's dried up just screw through it and it will all crumble out.Soak the bone part only in bleach overnight and coat with clear gloss nail polish.
