This is a brand new idea. Pocahonta's face has been completely redesigned with a 1 inch pedicle to accept the right side of a shed antler or cut off antler.  NOTE: this face can not be used to mount a wing, designed to attach only a right antler. 
Comes with a 3 1/2 inch lag screw to screw the antler onto the pedicle. Drill a 1 inch recess into the base of antler, drill a 1/4 inch hole in pedicle and  1/8 inch hole in antler, add a ball of epoxy putty in between and tighten down.
Comes with mounting kit. (same as the regular War Bird kit, but without the mounting block.)
