Interesting M4 but unlikely. The device in question is quite small making it difficult to see especially in a mood lit "gameroom". I know they had a pool table down there before Dads tools went viral but it was at the other end of the basement. There is no coloring to make the values more visable (black would be ideal).

Its certainly the best guess so far. My thoughts are it may be phone company provided although it goes to 9, not 12 so its not date related. Thanks for the submission! Gotta get back to the 4th axis! TD
