I got my sign from a dealer along Parramatta Rd but I think it was closer to the Vauxhall inn end
It was back in late 80's or early 90's I was heading for work & saw this place being either demolished or re purposed
Anyway, I was able to park & walk in (no worksafe back then) laying on the ground a little worse from the years & the removal from the roof was this sign in enamelled letters

Asked the only worker around if I could have it? fully expecting a NO but after a little begging i got a YES, couldn't believe it, but then I had to wrestle it onto my wagon
It's been painted white over the enamel but recently re started cleaning them up
