Found this brass name plate off an old explosion proof safe. Cleaned it up a bit.
Chased up the history of the makers : M.G. Dyke & Sons operated in Victoria from about 1880 until they were bought out by Chubb around 1970. At one stage in the late 1800's they stopped making safes and made pot belly stoves.
* Just found this workshop receipt/invoice for some lock work from the same company. Check out the date and header details.
