I have one of each, the 1 of 1000 and the 1 of 101. The Ruger/Lyman Centennial rifles (1 of 101) were engraved and gold inlayed by Robert Cane. The 1 of 101's accessories, tools, scope and cleaning rod are all numbered to the rifle. The book is the same but leather bound instead of paperback I did not drag out my case with the book, cleaning rod, cartridge cases and medallion.
