Bull,
If I was looking for anything having to do with hides, antler, claws, etc. I would try first Eidnes Furs in St. Maries, ID. If they didn't have what I was looking for, my next idea would be Moscow Hide and Fur in Moscow, ID. If I struck out there, I guess I would resort to Google.
Hope that helps somewhat.
John
PS Well, on second thought, I guess Eidnes has sold off and gone out of business. Here is an interesting article about both above businesses.
