It’s fitting that on this Anzac day I have been able to find out about several more companies that manufactured uniform buttons for WW2, and to purchase some examples. I’ll share images when they arrive by post.
Today I may have solved one of my mysteries! Up until today I didn’t know which manufacture was referred to in this article from 1934.
It was most probably Sheridans Badges, a family firm started in 1913 by Victorian born Charles Sheridan in Perth that still continues today. It had large contracts in both WW1 and WW2. See http://museum.wa.gov.au/research/research-areas/history/sheridans-badges for more on the history of this company.
