Charlie, I'm sure your train has left..........Jean.....Who was it (if you recall) who had a kind of tie-in to the epinette and the French background "relative?" I remeber reading an interesting summation of the epinette being used around Gallipolis, Ohio just about that time and that perhaps it too had added something. I don't recall where I read it though.
All the names attributed to sizes are pretty much as Jean says...marketing ideas/ploys. The configuration and tunings are still the same.
