Hi, I think
regross could be very correct. Whalers were very active in Tasmanian waters. This from Allan Carters site;
http://www.abc.net.au/treasurehunt/s983442.htm"Scrimshaw is the name given to carved or etched items made from whalebone, whales’ teeth, or from other bone-like material such as deer antlers, shells and walrus tusks. Items were either incised (etched) to create pictures or carved and turned to produce useful objects like baskets and sail-making tools.
Hobart was a very important whaling port from the 1840s to the 1890s and the quaint sandstone warehouses of the waterfront district from Salamanca Place to Hunter Street were then bustling with activity, reflecting the prosperity that whaling had brought to the state. At any one time it was not uncommon to have up to forty whaling ships in the harbour.
The whalers may have long since departed but Hobart is still Australia’s home of scrimshaw and both the Tasmanian Museum and Art Gallery and the W L Crowther Library in the State Library of Tasmania have large collections on display."
With thanks to Allan.
