Compass - Angelo Tornaghi
Angelo Tornaghi arrived in Sydney from Italy in 1855.
In 1866 his business was crippled by a massive debt and he was forced to sell all of his stock which included clocks, watches, jewellery and astronomical, mathematical, optical and survey instruments.
I expect that this compass was made before 1866.
Although the diagonal prism is missing from the compass it was still worth the purchase to have an item by this manufacturer.
After 1866 Tornaghi concentrated on making paving tiles alongside a specialized business for the making, installation and servicing of some of some of New South Wales important municipal and community clocks.
