Hi! That is replica of Mongolian wooden sinew backed bow of 13-14c. The original bow is at the museum in Mongolia now, I do not know of which wood is made it, but mine replica is of mulberry wood. I using deer sinew and fish bladder glue. Birch bark cover and linen bowstring. I do not cut down green (live) tree, it was dry (dead), the green leaves are of parasite plant.
