Hi Myrtle's Cook and thank you so much for taking the time to reply to my post. I'm glad the history of this concertina got you intrigued too - I love a bit of history and a mystery and like you say, I'm fascinated as to what connection this man had to Wheatstone to get what looks like preferential treatment! I wish I could find out the story behind it although all my various googling has turned up nothing so far.
Yes, it has a beautiful mellow sound and a great action which is exactly what I was looking for. I'm very picky about having a really fast action otherwise my brain and fingers start getting tied in knots. My other concertina is a metal ended and although has a great sound is very, very loud, My husband is a fabulous singer and with this new concertina I can finally play along without drowning him out!!
Thanks so much again xxxxxxx
