In Reply to: Using a Grafloc Roll back on a 'spring back' 2x3 posted by Mike Lee on January 24, 2001 at 09:05:21:
Somewhere on this site they talke about adapting a spring back 2x3 to fit a roll film back.
Graflex did it three different ways.
They made "adapter kits" This is nothing more that replacement springs and a couple of screws. The new springs have tabs that hold the roll film back into place.
Then there is the proper graflok replacement back, that was available for miniature speeds after the Graflok back came along.
The third method was to take a back from a Pacemaker 2x3 and put it on.
The differences between the last two are suttle. A Pacemaker back with have a round swing down peep sight and the top area has a radiused or filleted edge. The Replacement back for the Miniature does not have a peepsight since it's on the camera already and it does have the flash sync terminals to the focal plane shutter.
Since FP flash bulbs are hard to find I don't see a whole lot of functional differences between the two, but at least you'll know what's going on when you see a camera with two peepsights on ebay.
The adapter springs show up from time to time on ebay as well. I have no idea what they are geting, but do know that there were two sets, one for the mini speeds and another for the 3x4/4x5.
