Great, thank e kindly Cap'n. Ive got a diagram of L & R chord patterns off the internet some years ago and not really done anything about it.

By the way my concertina mender looks like Captain Birdseye (off the TV ad!!) Wont say who he is but he lives up on the Welsh Coast.

Ive had my concertina since I was 9 and used to mend it myself. In fact my mender asked if I was from Liverpool as concertinas from there seem to have been mended with odd things. Mine was held together with corn plasters for the dampers, old pink elastoplast cut for the valves and safety pins shaped to make the springs.

Since its been overhauled in 2000 I havnt dared breathe on it. It was tuned to Bb to fit in with a brass band or Sally Army Band.
