[LargeFormat] Apo Gerogons and Graflex RB Cameras

[Jim Hemenway]

Hi Clive:

My "D" has a chrome button on the very back edge of the right side, just 
to the left of the shutter winding knob.  It's very stiff and takes more 
effort that one would expect to push it in far enough to rotate the 
back... which is a Graflok back as well.

 >>> The back on my Graflex does rotate a little too easily. The 
positive lock doesn't! I don't recall how the Super D locates the back 
positions but it is probably similar to the older RBs. Mine has a detent 
pin that is supposed to lock the back in either portrait or landscape 
mode. The back has been replaced with a Graflok variety, probably many 
years ago, so it may be the case that it needs a bit of TLC. <<<
