Back in the late 1930's Graham producted car's with a crankshaft driven Supercharger. This spring I saw one of the Graham Superchargers on vendor table at the Carlisle Spring Swapmeet. The Supercharger had a plate on it that said "Supercharger Designed and Built By Graham" I really liked the plate. iIt had a simple style but looked pretty cool. I snapped some pictures of it and decided to reproduce the plate in etched aluminum. The orignal was approx 3" long by an iches high. Mine is a little bigger 6" x 2" to be exact.
