Sweet, sweet units you're making, Bryan. You're a VERY talented guy !
Would that Aussie maker be Peter Hyde?...he lives just a few kilometres from me here in Adelaide..
A friend of mine has the Bower Cajun model accordion...named after my friend actually.
They're nicely built..lack the power that the LA made boxes have IMHO, and the stops are fakes..Apparently Peter has his own opinions on the necessity, or lack of, for stops.
His accordions are nicely made but too ' folky' for my tastes...but each to his own, as they say.

That's him, Darryl, Peter Hyde. Seems a very nice chap. We've had some good discussions, and I just had to try it.
