Docter 240mm Apo-Germinar W for 11x14

[jurgenestanislao]

Hello,

Is there any resources online with regards to the lens coverage of the Docter 240mm Apo-Germinar W? I did a lens test on my Wisner 11x14 Technical Field and noticed sharp cuts on my edges.

Any leads or experiences with the lens would be very much appreciated.

Thanks,

Jurgen
