Does anyone know the value of a used, but in excellent condition Rochester Optical 5x7 wooden camera? It comes with a 6.5 x 8.5 back. On the front tag, it stated "Monitor, Manufactured by Rochester Optical & Co. patented in 1885". Is it true that this camera was once made or designed by Mr. Deardorff when he was an apprentice at Rochester Optical. It looks almost identical to the Deardorff camera. Any information would be greatly appreciated. Thanks much!
