This is a camera used at Taipei Museum / Taiwan to reproduce chinese art paintings , drawings and caligraphy. Camera lenght is 5 meters , Film widht is 2 meters. They ?roduce from the camera 12 color separations.

I used at different variety of films for argon laser to uv to daylight at prepress which roll width 120 centimeters to 30 meters. I think film could be from this kind of batch.

Who produces the lenses ? I cant even calculate the focal lenght ?
