The 2-player version of this game is Bally's 1964 'Bongo'. This game is the only Bally 4-Player to use a ball-lift. Pictured in this listing is a playfield having an extra-ball insert just below the playfield bingo card. This came from a German version of '3-In-Line'. We can trace ownership of this particular game back to 1980 in Germany, and the insert was present then, thus we figure it was added by a operator sometime in the 1970s. Also pictured in this listing are two backglasses showing the game name in white lettering, instead of red. The dresses of the three majorettes also are white, instead of red. One glass was reported to us as an alternate version. However, backglasses of this period were notorious for the red pigment washing out into a white color. Yet, other prominent red areas on these backglasses seemed to remain intact. More information is needed to possibly clarify this, including pictures of higher-resolution and/or close-up pictures of the dress areas.
