I remember her well from her working days in Sydney, having travelled on her a number of times when I lived there, and later, too. There's been quite a bit of alteration from her original condition to her current form as a floating restaurant and function centre as well, John. It will be good to see some more pics of your model.
For those who don't know, South Steyne was built by Robb's of Leith, Scotland in 1938, with a steam engine built by Harland and Wolff of Belfast. She left the UK on 7th July 1938 and sailed the 22000km to Sydney under her own steam, arriving on 19th September 1938.
She made the crossing from Circular Quay, in the Sydney CBD, to Manly over 100,000 times, carrying more than 92 million passengers during her 36 years of service. Quite an impressive record.
