Oceanic Club Question: Real Deal or Tourist Appeal?

[VANDOO]

UNFORTUNATELY IT IS VERY DIFFICULT TO PIN DOWN A LOCATION FOR THIS SORT OF CLUB AS THE FORM IS TO BE FOUND OVER A LARGE AREA. SOUTH PACIFIC IS ALL I CAN SAY FOR SURE
THE DESIGN USED MIGHT LEAD TO A MORE EXACT LOCATION. ITS NOT LIKELY TO BE FROM MAINLAND NEW GUINEA AND IF IN THE SOLOMON IS. IT DOSENT HAVE THE USUAL MOP INLAY BUT THEN NOT ALL CLUBS FROM THE SOLOMONS HAVE THAT INLAY.
MORE RESEARCH ON THESE SHORT CLUBS NEEDS TO BE DONE AS THERE IS QUITE A VARIETY OF THEM AROUND AND THEY REMAIN AFFORDABLE ESPECIALLY COMPARED TO THE OTHER LARGER MORE RECOGNIZED FORMS OF CLUBS FROM THE AREA.
HERE ARE SOME PICTURES OF ONE TYPE OF TURBIN SHELL AS WELL AS SOME OPERCULUM. THE COLORED ROUNDED SIDE IS THE PART ATTACHED TO THE SNAILS FOOT THE FLAT PLAIN SIDE IS THE OUTSIDE OF THE DOOR AND SEALS THE SHELL OPENING.
