If anyone is needs the elusive TNC ISO keypad overlay, attached are several PDF artworks (positive and negative, and mirror images). The one in the photo is laser-cut but the artworks are easily cut with scissors or exacto knife. These may be printed 1:1 scale on transparency mylar and the back side covered with a white overlay, or painted. Or the positive image may be printed on white paper and covered/laminated with a clear PSA film/tape. I had drawn a frame to mount the overlays, but isn't really needed, small magnets or tape work well without the frame. Cheers Charles
