Yagi, Is your friend's Lachenal also an Edeophone?

It's the batch number. On other places in the ledgers the batch number has it's own column. It's the number that in the production process is used to mark all the parts of a certain concertina.

Yes, Dirge. Please do.

Win Wakker of Concertina Connection wrote a great explanation about the airflow in our Concertinas: http://www.concertinaconnection.com/about_ airflow.htm

This question by Accordian is posted twice. I suggest to concentrate all reactions to the other "making a 40 button Anglo". So this one can be deleted when it's discovered by Paul or Ken.

Great to see so much practical knowledge gathered here, over and over again....

In the member section I found 282 posts by Göran. That's gives me the impression that none of his posts are deleted. But you're right, enough said about this...

No. I mean these arguments stopped the moment Göran was no longer a C.net member, and all that's was written is to be read in the archives.

Not true. Anyone can read all arguments. So no sides excluded.

Do you have a so called 'Mallet finger'? I had that once. See my reply to a comparable question in 2009: https://www.concertina.net/forums/index.php?/topic/8921-now-is-the-winter-of-my-discontent/&do=findComment&comment=88386

English system, 40 buttons... Leaving out the higher notes, compared to the standard 48 buttons?
