Ok, so this is apparently a pretty common mod to the R.B. Graflex cameras (specifically the 4x5 and becoming more common now the 3x4) yet I have not seen any tutorials for how to do it. I know Lens and Repro in NY will do it (for a hefty price) and I know there are places to send your camera but what about instructions for those who like to do it themselves. I'm curious as to what exactly is involved to do this to a 4x5 Super D. Is is so extensive that it is really only practical to send it out to have it done? I've heard that the Graflok back off of a Super Speed Graphic will fit directly onto a Super D, is this true? Anyway, can someone please provide some detailed insight into this endeavor? Thank you.
