Mills 1938 Horse Head Bonus, 5 cent, previously restored, powder coated painted brown, trim in gold with the Hard to find Bonus feature. New reel strips, new award card, original cash box, original back door with Mills lock with one key. Casting are (CAST IRON) not aluminum on this machine, not too many of these still out there.  

When the BONUS letters on the first reel come up in order, corresponding letters will appear at the top right of the machine. Once the entire word BONUS is spelled out, you win 18 coins. This was another way Mills would try to keep people playing longer and if you had almost all the letters showing, it was hard to walk away.
