It's been a long time since I picked up an early 1900's camera at a garage sale.
Today was my day.
American Camera Mfg. was bought by Rochester Photographic Co. which was bought by Eastman.
While it's labeled as a American Camera, I believe it is actually a Rochester "Cycle Poco 4x5" plate camera. "Ruggedized" so you could take it with you on your bicycle outing (meaning leather covering instead of finished wood).
