My Williams Flash has original playfield without a single dimple.
Two other EMs with no dimples (only some wear near ball kick outs on playfield).
3 Sterns (5 year old).......lots of dimples everywhere. Can't see them directly but on an angle view with lighting you can't avoid noticing them.
My conclusion (contrary to Steve's theory) is "They don't make them like they used to".....like all other goods these days in a disposable world.
