Bigbrownie, my basket is 50 years old. I never used it too hard since I had another user.
Moon, grandson of Clint Ishman, is still making Trapper's Pack Baskets near Brookville, Pa. very close to Rt. 80.
Made In Pennsylvania
Moon said to treat new or used pack baskets with Vegetable Oil.
It was surprising to see and feel the basket relax and become less brittle. A surprising transformation made me realize I was holding history, part of our heritage.
Bb, here's a contact number I got off internet, if interested.
