A conversion kit for Bally's 1979 'KISS'. An alternate set of playfield plastics is shown in this listing. Its owner obtained them directly from the manufacturer, apparently years later, as Geiger's employees at the time did not know anything about them or the reason for the two versions. Mr. Geiger has since confirmed to us that two versions of plastics were in fact produced but he could not recall the reason for that. He also provided the production run quantity for this listing. We previously showed a manufacturer date of 1985 for this game. However, the backglass shows the artist's date of 1981. Mr. Geiger has informed us that this kit was made in 1982. This listing shows two different styles of playfields. One has translucent inserts and one has transparent inserts. We don't know if the two styles coincide with the two versions of playfield plastics.
