I had a friend of mine make my first bird for a wall mount, he put it on his web site http://allseasonstaxidermy-maine.com/Testimonials.html
. I have since shot several nice birds, I had the biggest mounted on an identical plaque, but i had the legs freeze dried and hung on hooks right and left of the beard, My wife hates the feet. I had him do a breast mount on the same type of plaque, this time I had him just do the 1 inch segment of the legs with the spur on it.
If you look on hif photo gallery page he has other plaques he uses for multiple beard birds.
Not really sure if this helps, I like the way they look, I am currently in the middle of moving, but may be able to get pictures of the others if you want.
