I have just returned from an estate sale where I purchased a hand made longbow. It is about 80 inches in length, tapered at both ends, with a very slight curve. Approximately 1 1/4" diameter with a little bit of work done to flatten the face. The wood is very dark, almost black and has a grain like walnut. It has a very loose string of some kind of natural fibers. Draw weight feels like it could go 50#. The craftsmanship appears to be more utilitarian than decorative which leads me to believe I have found a real hunting weapon. There was also a bamboo arrow which was about 5 ft. long but it was trashed so I left it. (I may later regret that) Thanks for any help someone might be able to give in identifying this.
