Steve Gardham:"Good luck to you. There is absolutely nothing wrong with trying to improve something. No one is suggesting we should all throw our old instruments away".
RE:Thanks Steve! Wishing me luck is warmhearted but unnecessary since I am very happy already!I just hope others might get the fortune in their lifetime enjoying the same.

S:"I have often contemplated a more efficient and cost effect way of producing bellows, using modern materials and modern technology. Unfortunately I haven't the time or resources to do this".
RE: Despite being a habitual innovator I have rejected such thoughts regarding the concertinas since in real the soundsource itself is so comparably costly today.It was not 100 years ago.The soundsource of stringinstruments cost some £10-20 and a phantastic digital soundbox you can get for £100 while a reed set may cost 10 times as much.
The bellows *can* be massproduced and treated as comsumables but that hardly helps much...
