Here's an interesting find in via Justin.
If anyone knows what it is and/or has anymore info on it, let us know.
If you zoom in on the bottom pic, you'll see the controls, left to right, are as follows:
WA-WA with Mechanic and Range knobs, and switches below, one Automatic and one Rate.
INFRA-MODULATOR with a Power label below, and knobs for Rate and Range. On/Off and Rate switches below.
COLOR-OPERATING with eight sliders and eight On/Off switches. I'm guessing these are harmonic amount sliders with the ability to switch them off on the fly. So this is likely an additive synth. Curious if it sounds more like an organ or a synth. Also curious if it's monophonic or poly/paraphonic.
GLISSANDO / PORTAMENTO with two sliders and two switches. One switch is On/Off and the other appears to be direction. BTW, this section makes me think this is more synth than organ and likely monophonic.
NOISE GENERATOR knob with On/Off switch.
VOLUME knob
POWER On/Off switch.
Note the absence of envelopes.
Update: it kind of reminds me of the
Baldwin Syntha Sound. That one had a SPECTRUM SHAPER. Note the lack of a Baldwin label on the front of the Syntha Sound. The BB on the front could be for Baldwin, considering it's actually a mirrored B.
Update2: New pics in via Justin along with some info.
"I spoke to the girl who owns the synth. She said its a Czech synth and it belongs to her family and was packed away in storage for a long time until she placed it in her store as a display object. She said its not for sale."
The synth is located in a shop in Prague.
If anyone knows what it is and/or has anymore info on it, let us know. 
"Here's a rare Baldwin synthesizer from the 70's. Main issue is that the keyboard is not responding, but I was able to plug a guitar into the external input and do some limited testing.
"This is a very basic early synth but It all works including the built in speakers.
"One of the rarest keyboards out there, the Syntha-Sound is full of cool, unique sounds. This synthesizer is extremely rare to start with, but included here is a complete collection of its even rarer accessories: volume pedal; case; user manual (with additional instructional inserts); four die-cut plastic setting templates (themselves works of art); service manual; schematics."
"For your consideration is this vintage 1973 Baldwin Syntha-Sound analog synthesizer by Gretsch & Baldwin. This particular example, serial number 254, is in excellent 100% all original condition and includes the original leatherette cover! Not much has been documented about this very low production synth, other than the fact that it is exceedingly rare, and finding one in perfect working condition seems to be near impossible. Sold along side its more famous electric harpsichord counterpart, this would make an unbelievable accessory, and would perfectly complement it in every way. Fantastic for analog synth fanatics, and studios low on real estate but high on tone, this is a great piece for most anyone who enjoys interesting musical instruments and hard-to-find synths.
