Quoted from Dandelock:What is the stock flipper rubber color for this game? I've seen red and yellow. I ordered a rubber kit from Marco Specialities and it came with yellow, but it also came with a Bally Playboy sticker/barcode on the bag but a a Stern Playboy rubber instruction sheet inside the bag. Googling images it looks like a lot of both colors, maybe slightly more red.
Per the manual, p/n: R-406-3 red flipper rubber.
