Here are some extension rails for wooden cameras. As with the backs posted separately, I have no idea which camera any one of them will fit. Measure your camera and see if the details line up. They are $40 apiece, shipped CONUS, more elsewhere. Satisfaction guaranteed. Paypal fine.
#9 is a a pin and screw mount, pins on 3 center, rails at about 13cm on center (sorry about the mixed measurements, but it didnt line up easily with inches).
#10 is a center key and raised ridge attachment, with the rails 5 5/8 on center.
#11 is pin and screw again, with the pins on 4 1/2 center and the rails at 6 1/16 One pin sis much longer than the other, and pointed. See picture.
All are in excellent condition.
