Carl Zeiss Jena Protar 505 mm

hi, does anybody know something about Protar f9 505mm lens? I have been trying to find some informations about it but it almost impossible. I would like to know what is the image circel. does it cover 8x10?
thanks for your help .

See http://www.cameraeccentric.com/html/info/zeiss_4.html, p. 27. Its coverage will be at least twice that of the 230/9.

I found the information , the lens is between 1902 - 1907 year and cover the 10/12 inches, and that's all I found the lens. All information ends 480 mm lens
