Here is a 1980 Stern Nine Ball playfield.  This was a basic restoration.   As with ALL early Stern playfields, all inserts need to be pulled and replaced/re-glued.  We had  NOS inserts for this playfield so most of them were replaced with new ones.  The biggest issue with the original inserts is that they are very thin and are prone to cracking/dishing.  No stickers, decals or overlays were used in this restoration.
