The manufacturer flyer states this game has a polyurethene playfield. However, two examples of this game with serial numbers 186 and 554 have been reported to us as having wood playfields. Perhaps the manufacturer meant a thin polyurethane clearcoat is on the playfield. If anyone has this game with a playfield made of polyurethane and not wood, please contact us. The schematic diagram uses a hyphen to spell the name as 'Cherry-Bell' and indicates it is Model 990.
