The Ray No. 2 was a folding bed plate camera made around 1898 by Mutschler, Robertson & Co. in Rochester, N.Y.. It was equipped with fine lenses and shutters of its time, for example with Bausch & Lomb Unicum shutter. The camera was offered with a "multiple attachment" for making two pictures on one plate, this particular model is extremely rare and almost impossible to find.
