Do not have this camera, but the book "Kodak Cameras - The First Hundred Years" states:

No. 1 Panoram 105 rollfilm, format 2 1/4 x 7" Manf. 1900 - 1926
No. 3A Panoram 122 rollfim, format 3 1/4 x 10 3/8" Manf. 1926 - 1928
No. 4 Panoram 103 rollfilm, format 3 1/2 by 12" Manf. 1899 - 1924

If you have details of the lens and shutter fitted to the camera, I could date it more accurately.
