Thanks for the number. The stamping was so faint, I was using a jeweler's eye loupe to read it. There was a space in the number, but the thickness of the enamel gave no hint the there was a digit hiding underneath. Thanks for your gracious, encouraging words. The idea of finding unexpected treasures in drawers or boxes IS pretty exciting. Most recently finding Singer grease tubes in a couple of cardboard accessory boxes (including a black box - I had never heard of a black one), and a rolled up 27K/28K 5 1/2" by 8 1/2" manual rolled up inside the wooden accessory compartment inside a coffin top cover.
