I recently bought two cameras on Ebay and having hard time locating info on the cameras. Any info on them would be great. First one is "The National Camera": http://www.dropshots.com/photos/113859/20070123/043934.jpg. Any idea about age?? Second camera is Seneca Camera. I have been told was sold by Sear company. era 1901.(I think) http://www.dropshots.com/photos/113859/20070205/181911.jpg.
