Ann (The Creative Saddler, Parkesburg, PA) replaced the billets on my saddle in a week. She stayed late twice so that she could be there when I was available to drop the saddle off and pick it up when it was finished. She does lovely work, but has much work to do. She marches to the beat of her own drummer. But so do I.
Another repair choice would be Bartville Harness, 1243 Noble Road, Christiana, PA. 717 529 6992, M, T, W, Thurs 7-5, Friday 7-7, Sat 7-4, closed Sundays. No credit cards, only checks or cash. It is 10 miles SW of Parkesburg. They cut down a noseband for me while I waited, but obviously putting on new billets would take longer and require that you drop the saddle off. They make a lot of the Bit of Britain/Nunn Finer/Tory tack. BONUS: its a blast to shop for all sorts of all sorts of strap goods, racing supplies, stable supplies, and medical supplies.
