A "custom shop" article is a "boutique" item by any other name...
Surely it may be argued, that you could arrange for the
marriage of two,
"Legitimate and individual Gibson Custom Shop instruments", built to your
specific and unique personal specifications, but
acceptable to
the Company, that could, by the means of a chosen
"out-of-house" luthier's
alchemical magic, ideally an ex employee of The Company, so legitamacy and audit trails could, at the very least, be maintained; maybe they could even be persuaded to serialise them consecutively, or uniquely, for example UW3, if that sort of requirement is another necessity, and once completed, they would become
one, a unique and personal to you item that would be yours and yours alone, and then, with your legalese, you could persuade the hoi polloi of the merits of such a fine and unique addition to your most eminent collection... quite the talking point, I might add...
