To add to what James said, Grant wasn't interested in mass producing them, so he gave Gary Pearson, the go ahead to make as many as he wanted. Gary made quite a few, until his early death in 1998 of a Heart Attack while going through a stress test on the Tread Mill. Several copied them for their own use, until James decided there was a need in the Rimfire community and went into production of one of the finest one piece you could buy for the money. Several other made excellent rests as well, but for the dollar, the Pappas was still the best buy. That's why you will see more Pappas (Grant Pickard style) one piece rest on the line. James has done a fantastic job with the many innovative improvements to rests you see today. James is easy to work with, and if you want something special, he will accommodate you.
