Does anyone know who this girl is?
I understand that The R.A. Moog modular that she is playing is this one (bar some different modules in the upper right of the top case and the absence of the second keyboard):
The system includes:- three 901 VCOs, 901A VCO driver, four 901B VCOs, 903 White Sound Source, two 904-A LPFs, 904B HPF, 904C filter coupler, three 902 VCAs, three 911 envelopes, 911A dual trigger delay, 907 10-band fixed filter bank with a unique original switching system, and a five-octave keyboard
The basis of the system dates from August 3 1967. I understand that the picture with the girl was taken in the summer of 1969. There is a record of a second service being carried out at R.A. Moog when the extra cabinet & modules were added).
This modular is the 10th proper system sold by Moog since they started keeping records (based on serial numbers) at the beginning of 1967. Professor Emerson Meyers of the Catholic University electronic music studio used it to create the late 60s LP "Provocative Electronics".
