Beautiful old game Nino. Where there any of these sold new in Australia in the 1970's?
Back in the 70's pinballs were purely for operators. They were not sold to the public as they are today. When my father was an operator, he flew to the GTB factory and picked out the latest titles. They were NIB EMs that were imported in containers. He did the same for Bally SS games.
When I was a child, we had a few Surf Champs. I remember them well as Dad gave one to a school friend of mine to use for his Dad's beach house.
