The 355 G-Claron will have a larger coverage circle than the Artar, and will most likely be in a more modern, reliable shutter than the Artar. A 14" Commercial Ektar will also cover 11x14, at least at portrait distances, and may still cover at infinity with minimal movement. The 14" Dagor will have similar coverage to the G-Claron. I don't know of a 360 Nikkor that has that kind of coverage, but I'm not very familiar with the shorter Nikon lenses. I have a 450 Nikkor-M that covers 14x17 with room for movements.
