I'll have to have a look & see what Bally was pumping out & what size their factory was. Gottlieb's factory was 250,000 sq ft. So at times pumping out 300 machines per day WITH real competitors. Stern pumps out roughly 60, without competitors & had a 40,000 sq ft full facility until it's move (can't find what it is now).
Btw, is it true that the ogre in Stern's Shrek came out of a Happy Meal? It's in a seemingly reputable article, but that sounds a bit off key?
Yes, its true. Stern bought up the excess USA McDonalds Shrek toys for the machine
