While I was at Millmerran I went out to Ned Winters property on the Cecil Plains road. Years ago he started the camp oven festival on his property and when it grew too big handed the whole thihg over to the local shire. Anyway I had a long talk to him about ovens and so on and one of the things he said was he didn't like Furphy ovens, they are too thick and hold the heat, not a good thing in his opinion,  in saying that however he bought ten 20" ovens from Furphy when he was setting up his camp oven site for tourists, only has one left having sold the others off. I asked him if he had any old ovens for sale lol. no.
He uses Metters and similar old ovens of which he has dozens, does soup and damper for lunch, $10 a head eat as much as you can.
At the gate to his place he has two camp ovens made from tractor rims over 1 metre wide, no one has stolen them as you can't lift them!

Ned is in his seventies now and still doing almost daily shows for tourist buses and travellers but not for much longer as he is selling his property soon.
I watched him judging some of the cooking at Millmerran and just looking at the dampers he said, "Too wet a mix", or "Overcooked".
