'Wisconsin' was the first flipper game made by United. Pictured in this listing is a game that appears to have been converted not once, but twice, by an operator. The first conversion would have changed the cabinet from a standard game into a rolldown game by using screws to attach thick wood rails to the sides and front of the cabinet to allow for the two-level playfield glasses for rolldown play. A rolldown version of the playfield was installed which has no curved wooden upper ball arch. The shooter lane would have been blocked at its top end, and a ball cup installed in place of the spring-loaded ball shooter. The second conversion would change the game from rolldown back to a standard game. The thick siderails were left in place, but the small playfield glass was removed and the larger lower glass was pushed forward, leaving an open gap between the lockdown rail and this glass. The spring-loaded ball shooter was re-installed. Because the rolldown playfield was retained and does not have an upper curved wooden ball arch, a short curved metal strip had been placed at the top of the shooter lane. We have marked the images of this game as a "Rolldown Re-conversion" and present them as an example of what changes the operators might make.
