Sorry - we've never tracked individual models. There must be more than a thousand Distillates in their various forms, but I don't have a better estimate than that.
That's still an impressive number, considering they were a standard model for just a few years... (1978 - 1990-something?)
On Distillate trivia Mica, when did they become available in the U.S. markets? Seems like I read here somewhere the first ones were specifically for export to Japan... most of those I've seen were zebrawood, single AXY, and controls mounted on brass frontplate. (like Sonicus' Distillate)
