Well Dave, that's a very interesting thread that you point to. But I'm not sure it answers many questions. What does it mean by production basis? Did these instruments actually pass through the Alembic shop, or did they just buy parts from Alembic and install them themselves?
Even if isn't a great instrument, if it was customized on-site I would think it would have some collector value at least. (Not what I would call a knockoff.)
On a related subject, someone on the thread you refer to thought it would be interesting if the people at Alembic bought some of the illegal copies and branding for their showroom. I may receive a letter bomb from Mica for suggesting this but we all might consider buying them and donating them to the factory for that purpose, or for a bonfire!
