Rob,
If you are shooting off the shelf, I can send a nice piece of Leopard Seal Skin, it's Orange with Black spots. Makes a real fine rest. As for a nock, I gave up brass nocks in favor of tying one on with some string material. It can be adjusted by twisting it up and down the serving and makes it real easy to tune, especially when I am shooting a new string in and it's still stretching. It's easy to do, the directions are in the "How to" section, the "Adjustable" one by Ray Hammond. I can send some string material with the Seal Skin if you want it. Let me know, and Thank You for your service.
Dan
