I was given some jazz 78s by a terminally-ill man. They had been much loved by his father. I began to research them and also to buy them from country op shops. I love their history, their physicality, their labels, and their sound.

Columbia has been represented with their own subsidiary in Sydney since 1905.
Miller [M] provides information on catalog numbers: it appears that the first release under the Made in Australia indication is in July 1926 with the dark blue label, catalog number 0517.
Therefore, this record must be 1926-7, one of the earlier Columbia records made in Australia?
