The replay version of this game is Williams' 1965 'Alpine Club'.The reverse side of the backglass shows the mountain climber is silkscreened fourteen times. However, the backbox insert shows only ten lamps were provisioned in the stepping mechanism to light the climber. This shows a decision was made by Williams to eliminate four steps in this carry-over feature. While this decision likely was made before production began, if anyone has a Sample or Early Production game, please let us know, so we can see whether it has ten or fourteen steps of animation.
