Mills 1938 Horse Head Bonus, 5 cent. Previously restored, green trim in black, with the Hard to find Bonus feature. New reel strips and award card, original cashbox, original back door with Mills locks with one keys. Casting are chrome plated.

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.
