I have some Osage that is at least 5 years old, bark on. It has some wood bee damage but these are pretty thick staves. 8" +. They aren't premium by any means. I'm sure there are some bows in there somewhere. LOL. I would like to donate them to OJAM. I will get some pics and post if any of the selfbow society members are interested. I am in Broken Arrow. I won't be able to attend so they would have to be picked up.
