This board is also located at the Malvern Tramways Museum. There did not appear to be an Essendon WW1 Board, but I would think there was one. If anyone knows of the whereabouts of an Essendon WW1 board, I would be pleased to know - maybe it got overlooked and is still at the Essendon Depot?
I have created a number of local history projects for which you will find links on this blog. I am a community historian (ie, not paid) living in Essendon. The content of my Empire Called database (see the link to the PBWorks website) is the result of nearly 25 years' research. I began collecting material for the database of local WW1 volunteers in the early 1990s, beginning with hand transcriptions of Honour Boards in local schools, churches, clubs and so on. It was after this that the National Archives of Australia began making digitised service records available online, followed by the Australian War Memorial uploading Embarkation Rolls of the Australian Imperial Force. The Empire Called blog is a companion for the PBWorks website of the same name.
Time Travellers in Essendon and Flemington is set up in the same way, with a website and a blog to report additions to the website. The website is a vehicle to publish longer pieces of research that are too long for newsletters. It also includes various indexes I have worked on for many years, plus photos from various sources which I date and describe in greater detail. You may find something of use for your research.
