I've been thinking about it for a while... even in the Showcase Thread section here, Series basses outnumber guitars by at least 10:1, though I don't know what the overall ratio might be over 50 years. I expect there are cycles where more guitars were produced, and other periods where scarcely a few orders for them were filled. A time for this, a time for that... every guitar-maker deals with trends. I bet if pressed, it might be hard for even Mica to tell you how many there are, but she'd come pretty darn close, having pulled so many of those index cards.
Lately it seems like the Darlings, Furthers, Tributes have taken frontline to the Series guitars, at least in demand. As a potential customer for a future Custom build Alembic guitar, I'm paying particular attention to the various guitar model specs. Details, you know... so many details.
