Quoted from Fur-Fish-Game - June 2010
"The folks who buy squirrel and fox tails for Mepps Fishing Lures also BUY deer tails. Write to: Sheldons Inc, 626 Center Street, Antigo, WI 54409-2496. Ask for a purchase order before shipping as they only take so many tails each year. The bone must be left in and the tail salted so it does not rot."
I would also try Orvis, Cortland and Erie Dearie.
