Thanks to everyone for the advice. The more info I can gather the better decision I can make. I will closely review all that has been submitted and will also use the links provided for additional material. From the proceeding posts I gather there are 3 or 4 distinct varities of concertinas and a clarification on the following points will assist me greatly. Are Anglos, English and Duets differing varities (such as Ford, Mercedes & BMW motorcars for example)? Or are they like Ford Escort, Ford Thunderbird & Ford Crown Victoria? Or is it more like a left hand drive as opposed to a right hand drive? I apologize for the poor analogy but it was all I could think of at the moment. Also Stagi and Edeophone were mentioned...is one a manufacture and the other a model?
I promise to not ask any more neophyte questions until I have read some texts on concertinas in general.... Thanks again, Wayne. Oh, by the way, I'm located in Tallahassee, Florida, USA and am interested in religious and folk/country music. HWPELT@yahoo.com
