These are 2 toned chrome Sierras. One of them has been converted to a pencil using the method that Mudder came up with. The puzzle kits are made by Constant at Lazerlinez. The finish is 8 coats of thin CA folllowed by a quick buff.
Beautiful set Neil ! I just may have to try one of those puzzles . Need more info about the pencil conversion . Sometime in the near future .
