Brett,
I finally had a chance to look at your pics. This is definitely one of the early one supplied by John Gabbanelli. Mr. John gave me all of the parts to assemble one excluding the bellows and reeds. It is identical to the one he gave me. They were all painted black because he used inexpensive woods. He would sell the parts to Marc for $75. Marc would assemble them and put finishing touches on them, then sell for $700-$800. Mr. John felt like he was getting the raw end of the deal so he stopped supplying them.
I have also seen a couple of the later ones that were supplied by the factory currently owned by Polvrini. They are identical in every way to the Gabbanelli Cajun King, including the slider assembly and frame routing.
Link #2 shows the Polverini Cajun kit. Looks like it would be fun to tinker with - but you might get hooked and end spending a lot of time in the shop.
