Some Concertinas Are “harder” To Play ? in General Concertina Discussion Posted June 17, 2006 I think that another issue that can be considered is that there are differences within makers which include date it was made, model/grade of instrument. I have a 1914 6-sided Wheatstone english with raised ebony ends and metal buttons. Yesterday I got together with a friend who has a 1960's wheatstone english with metal buttons and flat metal ends (it seemed that it is aluminum) I found that my concertina played faster/smoother, and had more volume and a much different tone than my friends. In the past I owned a a 1920's wheatstone english with flat metal ends and metal buttons which I beleive was not as responsive,etc as my 1914 (current) english.
