One of the magazines which I picked up had a very detailed account on the Scovill Panoramic Camera written by Mike Kessler.
The Scovill pano camera was made in USA by the Scovill and Adams Co. in New York. The patent for the camera was granted to Mr. Mathias Flammang, an employee at Scovill.
I hope you'll enjoy reading about this camera and please provide me information if any you seem relevant to this or other related cameras.
