Subsequent to posting I found a Regal on Elderley Instruments website. Though discontinued it was priced at about $600 when sold.
It is described as a Germany instrument adjusted by Marc Savoy. This rang a bell. I remember Marc saying he was advising a German company when I bought my Acadian in the early 90's. I wonder if this was the end product?
Phil...I have a 'C' REGAL on EBAY at the moment that also came from Savoy Music - about 10 years ago. At that time, Marc indicated that he had a hand in the setup...being new to the accordion, I didn't press him for details of 'setup'...I would report that the REGAL I got from him is a very serviceable beginning to mid-intermediate instrument that works just fine...although I agree that it is several jumps away from a Louisiana made accordion...should you buy a REGAL, I think you'll be quite satisfied for the price...
Regal's are very decent factory-made boxes. My first accordion was a Regal which I purchased from Larry Miller.
All in all it's a great student model, vastly superior to the Hohner, but several steps below a hand made. I still have mine and I occasionally play it just for fun...plus I don't have to worry about knocking it around too much.
F would be a bit high for my tastes, but it could still be fun to try out. From what I can tell, the buttons have been changed (improved) on that model. Also, I don't recall ever seeing one with crawfish bellows (as far as I know, this a trademark registered by Junior Martin).
