That "Concertina" advertized turned out to be no concertina at all, but a small accordion... so I'm still shopping. One source advised not to look at a potential buy without an experienced concertinist in tow. I only knew one in the State of Maine, and have not seen him in years! Any Maine squeezeboxers out there I can call on in a pinch? All this expert advice is really helpful - much obliged, Mates! "Uncle Jaque"
