Back in March, I put up this post on the mystery of who owns the first production Minimoog. At the time, there appeared to be two contenders: The Eboard Museum in Austria has a unit that they advertise as being S/N #1001. The Audities Foundation owns one that several third parties who have seen or used it claim is #1001 (the Foundation itself made no such claim, which should have been the first clue, but there was a confounding factor which I'll get to in a moment).
The Moog Archives seems to have resolved the dilemma. It now appears that the Eboard folks do in fact own production #1001. Audities also owns a unit #1001 -- but it's not a production unit; it's a prototype Model C! (All of the vintage production Minis are Model D, except for the handful known as the "Welsh Minis".) The Audities photo that I reproduced in the March post is not this synth. Here is that synth:
Note a few things about it. The big thing is the pitch and mod wheels -- they are completely different from anything that ever appeared on a production Mini. In fact, I'm not sure that they are wheels at all; they may be sliders. Second, note the A-440 oscillator switch; it's a plain toggle switch rather than the typical rocker, and it's a bit to the right of where the production Mini has it. Third, the pilot light: It's higher up on the panel than the production article.
(The thing sitting on the panel that covers the keyboard keys' hinge mechanisms appears to be a ribbon controller of some sort. My guess is that it was added later.)
I had speculated in the March post that Moog may have assigned serial numbers to prototypes and then later re-used those numbers for production units. And sure enough, it appears that that's what happened here. Another clue to the Eboard one is the white-background logo plate, whose legitimacy I had questioned back in March. The Moog Archives now says it's legit; it's the earliest version of the R. A. Moog logo. Unfortunately, we don't have the Audities one to compare to; if it ever had a logo plate, it appears that it was removed when the ribbon controller was installed.
I think we can conclude that the Eboard Museum legitimately has the first production Minimoog. The Audities Foundation has a prototype.
