Best of luck, Sorcha.
Aren't bureaucrats just the greatest advertisement for democracy/freedom/anarchy/despotism/pick an -ism?
Cleaning out an office recently I came across some PVC pipe that had been used as a mailing tube for Landsat prints... as an element in a thongaphone it would be approx D below middle C.

Foolestroup,
On the Ausfolk site recently (after my post above) there was some other chat about transporting instruments by air and dealing with/avoiding damage to them. I made similar comments on that site and decided to Google "Aerolyte Australia" and found they're still in West Heidelberg. I am assured that the Australian Folk Alliance website is setting up a collection of horror stories and preventative measures but I've been flat out like a lizard drinking and haven't been able to follow it up yet.

Cheers, Rowan
