After slitting open the bag to the shop-vac and sorting through every tuft of dust, the puzzle piece was not found.
So we fired up a paint program, found some cardboard, and screwed the blade into the Exacto knife. The piece is a little off color, but it will do. (The coloring should have been my job. My patience is stronger than Lyman's, and my sense of color is better, too, but my computer is not printing right now.)
We'll call that our piece of the New York puzzle.
Every picture tells a story, don't it?
