I understand Trick Brothers built accordions in Toledo Ohio until early into US involvement of World War II. They also operated locations of accordion schools before and after that time. I’m in the process of going through leathers on a full size 3/5 LMH. The instrument appears to be later than i understand the brand was building their own instruments (I’m guessing late 1940s or early 1950s.) possible a stencil arrangement with an Italian builder? The reeds have what looks like a dog head? Logo on them. Does anyone know this logo?
