Byron Deveson and I have independently been reading up on the Electrolytic Zinc Company: newspaper summaries of its annual accounts for 1947-1948 (here also) show that it employed 1709 staff at Risdon plus a further 432 at its Rosebery mining operation. It was in the process of expanding its wharf at Risdon, but was generally hampered by staff shortages.

As Byron Deveson noted in a comment a few days ago, the Incharran and Era steamships traversed well-worn grooves, keeping the Electrolytic Zinc Company’s Risdon works supplied with zinc concentrates (both from Broken Hill via Newcastle in NSW, and from the company’s Rosebery mines on the other side of Tasmania), and then passing the lead-rich residues of its zinc extraction process onward to the huge lead smelting works in Port Pirie. At Port Pirie, the ships would then get loaded with calcines and drums of acid before returning to Tasmania. (Note that Risdon is treated as an output of Hobart.) And so it went on.

Note that on 17 Nov 1948, the Incharran, Moonta and Cheltenham vessels were (along with various buildings in Port Pirie) bedecked with flags to register people’s delight at the birth of a son to Princess Elizabeth and her husband the Duke of Edinburgh.
And finally: I’ve just started putting together a list of Somerton Man “known unknowns”. Which is just a clunky way of saying ‘a page full of things I know (pretty much) exist, which I haven’t yet seen, but which I’d like to’. Please feel free to suggest other things that should be on there, or ways to see any of those things (and so remove them from the list)!
