Interflip is the name used for export games. The same company made a 1-player domestic version as Recreativos Franco's 1977 'Dragoon'. The manufacturer's flyer show pop bumper caps that are round and white, attached to orange pop bumper bodies. Some games in the production run have caps that are square and white, attached to white pop bumper bodies. The flyer also shows the two yellow targets in the lower playfield are labeled to score "5,000 points & Advance" while other games are labeled to award only the 5000 points. The kick-out hole plastic cover on some games is blue and on other games is green. Reportedly, there are several games in France that have an extra zero below the 30000 insert on the lower playfield. In the two images we present of this, the zero to the right of the 4 appears to be different as well. One game has serial number 00930 ink-stamped on the lower cabinet inside wall. No serial number was found anywhere on the cabinet of the other game but the front edge of the playfield had a handwritten number 6178. We do not know if that number was placed there by the factory or by an operator. Two game owners have each reported that their games were factory-wired for 3-ball play only, pointing out there is no operator option for 5-ball play. That is likely how all the games in the run were made, because a section of the schematic (shown here) indicates a factory 3-ball setting. To change to 5-ball play requires moving a soldered wire to a different terminal on the Ball-In-Play unit. We are seeking a manual or equivalent manufacturer documentation for this 4-player version.
