I Do Not Know Much About Cameras. This Piece Is From My Families Collection Of Antiques. I Remember As Far Back The Mid 1950's This Being Displayed In Our Families Home Up Till Recently. I Was Told It Was My Grand Fathers, He Was Born 1890. In Researching This Camera, The Only Thing I Learned Was The Bellows Seemed To Be Very Good, The Shutter Worked And The Overall ConDion Seemed Above Average. Fell Free To Email Me Any Questions Or Advice on This Piece.
