My father and all his best mates were Real Estate Agents in Forster Tuncurry for 20 plus years.
I know Peter Revell who was/is a Ray White Franchisee for many many years who still owns shops in the Main Street of Forster may have a whack of photos.
I grew up in Forster Tuncurry and went to High School there.
The one at the Tuncurry side of the Bridge had many names over the years, with different names, but for its last 3 or 4 years it was simply called "The Arcade". It was indeed called "Pot Black" when it tried to specialise in Pool and Snooker Tables.
I still love that area although I live now on the Gold Coast , Queensland.
Forster Tuncurry is still a very nice and beaut place to visit.
Look forward to your photos. Let me know if u want me to try n russle up some from my contacts/Dad.
