Andrew I'm not sure if you realise that the Old Melbourne Gaol referred to in Picture Victoria is not Pentridge. The latter is in Coburg of course whereas the Old Melbourne Gaol (which I've never visited) is in the city). When executions began at Pentridge the gallows beam was transferred there from the Old Melbourne Gaol. I remember it as painted white, and with notches in the top, presumably made by corpses swinging on the rope. The trapdoor which was actually a landing connecting the first floor rows of cells was tested regularly: occasionally you'd hear a Whumph! late at night. Prisoners who'd been hung there were buried just outside the back wall of D Division, and with nothing to show there were even graves there. I think the initialled bluestones were most likely from the Old Melbourne gaol, not from Pentridge.
Of course you are correct Robert and I may well have gotten that wrong, although I do know the difference. Just careless and I better fix it somehow.
Bah, why bother, it's a minor thing, your postings are good enough to allow little glitches.
The inscriptions are now buried, just like the lost souls they represent.
Regardless, I fixed it Robert.No need to disturb them Ian.
