She looks to be in pretty fair condition. A Lucky find. I remember the name Hercus from my apprenticeship days. I grew up in Adelaide And did my apprenticeship at Lightburns only about 15 mins from the hercus factory. When i was looking for a lathe last year I was unable to find any Australian made machines, in the size range I wanted, that were in acceptable condition, so had to settle for a taiwanese model, still running it in but so far quite happy with it.
Lightburns that a name I haven't heard of for years, I remember their washing machines and cement mixer when I was a kid.
