Unfortunately, playfield numbers arent the best way to track machine build numbers, because u can have playfield number 1014 placed into machine build number 880. I have seen this on alot of newer Sterns. They obviously make more playfields than they do games because they get made in batches and they have to produce an overun for spare playfields.

What I would like to see on this gents Ironman is any other machne numbers under the playfield, espescially under the apron area but on the base of the playfield, as well as on the playfields end face, apron end. These stickers are there 95 percent of the time, u just have to look hard

Either way, it seems Iron man may have reached around the 800 to 1000 ? numbers. Finding the correct numbers on this Ironmans under playfield could be the key.
