The Melbourne and Metropolitan Tramways Board was formed in 1919 and began taking over the several private tramway companies operating in Melbourne. Each of the private tram depots appears to have had a depot-based Honour Board. This one commemorates those that died, presumably across the various tramway companies. I don't know anything of the history of this Honour Board, but it is located in the museum next to the Malvern Depot. I don't know where it originally hung, but would be pleased to hear from anyone that does know. I haven't checked all the names yet for my particular interests, but I see that an Essendon lad, Roy Gordon Sumner, a tramways employee, is included
I have created a commemorative online database of the WW1 volunteers of Essendon and Flemington in Victoria, with a blog to support the website: see link below.
I have other websites and blogs which follow other interests.
