Hello all.
Simply a question of curiosity. I'm currently working on two Williams Hurricane machines simultaneously. Upon taking the first one apart, I was surprised that the pop bumpers had no lamp sockets in them. The other one does and they flash throughout the game. I assumed the first one had blown lamps.
It appears there never was pop lighting in this machine. No staple holes. Were some Hurricanes like CFTBL? Lighting omitted to save coasts??
