Mills 1938 Horse Head Bonus, 25 cent, previously restored, painted wrinkle blue,  with the Hard to find Bonus feature. Replacement reel strips, replacement award card, replacement cashbox, original back door with replacement lock with one key. Casting are plated. 3-5 payout.

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.
