When did Gottlieb start putting a last ball in play and game over light on the wedge heads. It must be between 62 and 66 as my Cover Girl has neither and my two Cross town has both, Hurdy Gurdy has just a game over light.

Sing Along has those sand resistors across the four kick out hole lights, I guess Melody and Kings & Queens have, as well. For the game over light, the resistor value could be increased and a normal 44 / 47 fitted. It certainly needs a higher value if the game is high tapped, even with a 455.
