I went through my cane stash and I have two dozen shafts in the spine range your looking for. I had to straighten them to get a spine value so they are straight but I havn't sanded the nodes and they go from 36 incches to forty four or so inches long. twenty one are well dried and are light brown color and I had to get three more to make two dozen from a more recent batch that are pretty dry but our humidity is very high here and they are still a little darker color. I could sand them all too for the right trade.
If your interested in them all or part of em let me know and we can work something out. I'm really interested in knappable materail, billets, feathers or no tellin what else, get with me.
