 Faceplate artwork for 888A

Joe K9LY from Chicago needed a new 888A dial plate for a restoration project. A friend of his, Mike - KA9CLP, was kind enough to lay out the dial scale on his computer for him. The original scale was in truly terrible shape. Nearly half the original scale (including the base paint) had been rubbed off by some overzealous cleaner. Then a very non-original looking paper scale had been stuck over it! A local sign-making shop had a large-format printer that printed the new scale onto a sheet of thin, gray, self-adhesive plastic. Then Joe applied it to the metal plate and carefully cut out the opening for the fine-tuning scale window. Joe thinks this layout could be of use to other 888A owners if they have a seriously bad-looking dial plate.
