This is the CP2 manufactured by Black and Decker in Croydon, Victoria. I have evidence of this model being on the market from 1963 to 1966, however I suspect it was available earlier and for much longer. This particular example belonged to my grandfather, who was a cabinet maker in Cooma, NSW. It was after inspecting this drill and discovering it was made in Australia  that inspired me to look into products manufactured in Australia and hence this study on power tools.
