So what were nos playfields like when the games came out. Were they just dimpled?
Wms
all T-nutted & dimpled if close to the end of the games run.
followed by dimpled only
then thirdly not dimpled ( these were usually the WMS rejects that didn't make it as far as the dimpling machine. or they had started a new pf/game and had loaded a new dimple plate
Sterns are at lest dimpled (as they do theres in house)
