Looking forward to seeing pictures. I love that East Indian Rosewood. For me, I always finish the insides of my calls with oil. Of course, that is what I put on the outside too, but then I buff the outside, ending with carnuba wax. Can't do that easily inside, so I just finish with several coats of oil. As to the signing, I usually sign the inside of the barrel. Seems like it will last better there. I am trying to get some decals made, and then maybe I'll use them. Depends on the call. For a call that may sit on the shelf, I kinda like the signature inside better than the decal. But if i can get them made up, maybe I will put a small decal inside the bell. That is pretty permanent and doesn't distract from the call at all.
