Pope Products or Pope Industries were and still are an Australian manufacturing business, now approaching 100 years of operation, although under different ownership at varying times. At some point they were making diecast items.
A Pope Product diecast toy is quite rare within Australia. I can find very little information about them.
A history of the business founder, Sir Sidney Barton Pope, can be found in the Australian Biography section of the National University archives.
The Guide to Australian business records site lists the history of the ownership of the various Pope business names and that from 1931 to 1945 it was known as Pope Products Limited.
The Wikipedia entry for Pope Products does not mention toy cars, but does list toy cap guns among the products. A search via Google reveals lots of meat mincers and washing machine information, as well as the current ownership and focus on gardening products.
There are at least 3 gun variations that I can find referenced, a single shot gun and a repeating gun, a Supa-Fort(ress) B-29 plane and the one Buick sedan but no other cars.
There is also a reference to Pope being a toy maker in Redfern in Sydney in the Australian Metal Detecting and Relic Hunting forum and that is not inconsistent with the idea that the toys may have been a small toy maker taken over by Pope but there is no other reference supporting that.
I am seeking more information and advertising material if anything exists. If you have know anything about Pope Products making die-cast toys please contact me with any information.
