Busch Optical Mfg. Co. in Chicago, Illinois (USA) was a camera maker, also known as Busch Precision Camera Corporation. It was famous for its versatile press cameras. Characteristic metal bodied Busch press cameras had an optical finder and a big sports finder as additional means of image preview, and most models had also a rangefinder. These folding bed view cameras allowed lens board movements and professional flash photography. At least one model was sold under the brand name of a retailer. Of course the cameras were equipped with fine lenses and shutters, for example the Tower Press camera with Schneider-Kreuznach Xenar lens in fast Synchro-Compur shutter. Some old Busch press cameras might not have its original lens/shutter set today.
