3D World TL 120-1 Medium Format Stereo Camera EXTREMELY RARE

Description

This is an extremely rare camera. As far as I know, only about 300 were ever made.
I have fully tested it, and found it is in excellent working condition all around, except for the exposure meter, which is not working. This is easily worked around by using an external meter. I used an old Gossen Luna Pro handheld for incident and reflected light measurement, and also an Olympus OM-4's internal spotmeter, both with perfect results.
I will consider any reasonable offer.
Please contact me for any questions.
