Quoted from wrd1972_PinDoc:

That is precisely what I saw on a new Elvira LE last week. Thay are not dimples, but rather craters.
According to this, Steve Ritchey says its normal.

I reckon there is nothing to see here. FTR, I have yet to find a dingle dimple on my 90's William's Bally pins.

Quoted from Mrawesome44:

I bought a tmnt LE. Had the 1,8,9 diverter issue. Let my distro know i need professional help to get it fixed. By the next day Stern and my distro had someone out to help fix my game. This was my first NIB stern and while my issue was resolved at this point I do not think i will ever buy NIB again which is sad because i was gearing up to buy a JP premium(or LE if i could find used) The frustration i felt having my game out of commission at 0 plays. Well lets just say i have a Newfound respect for those who buy multiple NIB and or waiting for customer service to fix their issues.
