Flash had 19,505 units produced and yes, they could have made more. This was in the days when the larger pinball parlours had 4 to 6 same title machines on their release. I remember some of the parlours on George St. Sydney with 80+ machines. From memory, there were about 16 Williams Flash spread around the various parlours on George St. In 1979. Bally machines were also very popular in Sydney around 78/79.
