I am going to plan a trip to the STERN factory later this year and maybe go with another few AP members who have also expressed interest.
I am going to politely ask Gary Stern for a ballpark number of machines made etc for a few different titles. All he can do is tell me to jump or he may just politely give me a ballpark idea. I was also going to ask some other common questions about the production line and some general interesting info about cabinets/re-runs and LE model numbers n pinball title planning etc.
