Here is most of an Eastman Improved #2 7X11 camera. It does not have the 7X11 back. But it does have 5X7 capability but it requires 2 screws to remove the 8X10 from the adapter and install the 5X7 with the 2 screws. A little different. Takes about 30 seconds. So if the moonrise is lighting the crosses, you better not try to switch it in time. 210 G Claron covers 8X10. Bellows are tired but I could use them with a dark cloth wrap. I wouldn't buy new ones, but everyone's threshold is different. $525 + shipping / offers
