G'day Hero John,
Rowan: further to my previous comments about the harmoniflute; the name written inside is: Chat Newark, Ballarall, Australia. and the date 1857.
Did you have a typo? I suspect you mean "Ballarat" but 'you never know until you ask'.

I'll not be able to check the one that, 20 years ago, was at Nariel until I get there at Christmas and even then I'm assuming it is still in the Klippel family.

Cheers, Rowan
