Jim already nominated the Orwick 64. I thought I would add my vote. The Orwick features a nice green crankcase and polished aluminum parts. Some of the green Orwicks were hammertone green, smooth green, or "wrinkle" green. The originals were either made by Henry Orwick, or factory-built by Al Cunningham. Recent replicas were by Joe Klause, Dunham, and others. None are in production now.
