I think this is a very early cover, for the first Melbourne water supply system which was turned on in 1857 with water from the #yanyean #reservoir. That company was taken over by the MMBW (#melbourneandmetropolitanbaordorworks) in 1896, so it could just possibly be 1857. But probably later. Spotted on the footpath in #collingwood, but I can’t remember where!
