I've just purchased a East German Anglo concertina here in Brazil (concertinas are not usual in this country) and was lucky since It was inexpensive - less than US$100 - and in great condition.
I research for it's brand "BM" and couldn't find anything, but in my search I've found similar ones made in Klingenthal as Scholer, Galotta and Rosetti Rambler. Does anybody know anything about BM and why there is no mention to that brand in internet?
My instrument is a 20 button D/G and has two reeds per note, but the second button on G row at bass side which should be D/E (according to the standard 20 button D/G layout), in mine sounds D/F#. Other 19 notes sound as expected, althought a little out of tune. Is this right? Are the D/G Scholers, Galottas and RRs tuned like that?
