The big daddy of the synthesizer family, the Model D is what most mono synths want to be when they grow up. Reissued in 2016 by Moog with identical thru-hole circuit board layout and components to the originals as well as an additional LFO and aftertouch and midi capability, this particular Model D has also been upgraded with the MUSE board (~$500 value, see here) which fixes some bugs, improves midi functionality, and adds cool features like additional aftertouch routing (aftertouch to mod-amount!), a dead-band on the pitch wheel for repeatable pitch stability, and adjustable ranges on the pitch and mod wheels. Very clean, freshly checked and tuned on the bench here. A great instrument for a home or professional studio, this is the last mono synth you will ever need. Comes with the original manual and Moog paperwork in the original box.
