Gilly if all else fails - there is a 30 button C/G Lachenal Anglo for sale in Brisbane Australia, just freshly restored by Aussie concertina-maker Richard Evans.It's had almost everything worked on and new reeds.I can vouch for Evans' repair work, and he made my own 32 button instrument. The one for sale's going for AUS$3,000, that's about 1,200 pounds sterling.

It's not mine, but owned by a friend of mine Derrick. His email is deke@ecn.net.au

Good luck
