According to a pinball club in Brazil, 'Shark' is the only game from this manufacturer that has an original playfield design (not a copy of a game from another manufacturer). Pictured in this listing are two stripped playfields. One shows unpainted wood in the usual areas at bottom of playfield, in the shooter lane and along the playfield edges, as seen on production examples of this game, and in its lower right corner are manufacturer's numbers. The other one has these same areas painted and the numbers are not visible. If this painting was done by an operator or game owner, we question why they would bother also painting the top and side edges. More information is needed to understand if this painting was done by the manufacturer. This game was also made as Fipermatic's 'Shark'.
