Having seen Nino's post, it reminded me that I had some flyers somewhere in the house. After a short search, I found them:
Stern: Wild Fyre, Dracula, Hot Hand, Magic, Trident, Meteor, Pinball, Genesis
Gottlieb: Totem, Pinball Pool, Count Down, Genie
Bally: Evel Knievel, Kiss, Eight Ball, Capt Fantastic, Mata Hari, Supersonic, Paragon, Hi Deal, BlackJack, Lost World.

I also founds letters I had received from:
PW Carrington, Operations Manager, Goddard Distributing Co
Thomas Nieman, Director of Marketing, Bally Pinball Division
Thomas L Herrick, Vice President Marketing, D. Gottlieb & Co
Lex Davidson, Automatic Music Co (Australian Bally distributor)
Ron Crouse, Marketing Director, Williams Electronics
Lawrence Siegel, Vice President Sales, Stern Electronics

These letters were received when I was seeking information about pinball in Australia in 1979.

Hey Mark,

How cool is that! What was the content of the letters?

Are you able to scan and post here if they would be of interest to the rst of us?
