Nice find! Congratulations!!
A couple of observations, what I believe to be the lower limb appears to have taken a very small amount of set based on what I can see in the 1st picture.
The brace height needs a little tweaking based on the second photo.
All in all, it looks like a great old Osage/hedge longbow.
I'm having some difficulty seeing the tips clearly but they look as if they've been glued on, maybe some sort of cow horn. Is the small white dot a piece of antler inlaid in the riser as a strike plate?
God bless,Mudd
