Ok, as I red your answers and did some other research, it really seems to be Carlsfelder made by ELA. I've also found another diagram that fits exactly to my concertina, just some label numbers (and so do the tones?) are different. If anyone's interested, here it is: There are much more diagrams for concertina, chemnitzer, bandoneon and accordion: http://www.korbo.com/piedcrow/DiagramIndex.htm

Thanks a lot for both of you. The excursion to the history made me feel more excited about my concertina, particularly the fact it could be so old... older than I supposed and that it seems it's really connected with such a name as Arnold. I also appreciate the links for instruction book, I'm just not sure if it would be so helpful as I don't speak German. Let me ask one another question about Carlsfelder 106 diagram you posted, Daniel: Could I count on numbers labeling each button? Like on the left side there is just difference in position of 14 and 17 button - so I think it might not be so difficult the identification of the notes? But the right side is quite different - on the 106 diagram there aren't any 2/0, 3/0, 4/0, 5/0 and 6/0 button... Any idea what does it mean? Thanks again

I would like to ask you for an advice. Few days ago, I get an instrument - perhaps chemnitzer/carlsfelder concertina (it seem closest in appearance to me, I don't know the differences between those types) - but as I went trough the internet I realized that none of the keyboard layouts that I've found fitted to my new squeezebox. It has 88 tones (24 buttons on the right side and 20 on the left - arranged in 3 rows on each side), an "A" in decoration (so it would be possible connected with Arnold family?) and there was a text I'm not able to read (something with 88 tones...) and pencil written date inside (12.12.14). I uploaded some photos in my dropbox gallery: https://www.dropbox.com/sh/i36l35953it77mu/x_GRp1-_rB so you could see what do I speak about. I would like to learn more about and to play this instrument. Could you help me to identify it? Do you know where to find a particular layout for this type? What about tunning? Because the numbers of buttons are not clear visible on the photos, I write them also below: LEFT 16, 1, 2, 3, 4, 0 15, 5, 6, 7, 8, 9, 0/1 17, 10, 11, 12, 13, 14, cross RIGHT crossed zero, 2/0, 0/1, 1, 2, 3, 4, 0 4/0, 3/0, 5, 6, 7, 8, 9, 15 6/0, 5/0, 10, 11, 12, 13, 14, 16 Thanks a lot, Barbora
