    It is two completely different systems.

    1) Graphic Back

    or

    2) Graflex Back

    if you have one, you could always put a sheet of paper in it ..
    then TAPE it on the back of your camera and see for yourself if
    it affects image sharpness.
    i have a 4x5/D and for years
    i taped a polaroid 545i film holder to the back
    and photographed with it. film cost at least 2$ / sheet
    so i wouldn't have wasted my time oR money if it affected focus.
    and CURRENTLY i have a graphic 23 roll film back (made for a camera with a modern international/graflok back )
    it is TAPED on the back of my camera ( series D that like yours takes notched holders )
    ... i have shot maybe 200 rolls of 120 film with it. my lens is usually
    a brass lens with no aperture, or a 210 tessar shot wide open ( 3.8 ) again
    it doesn't affect much of anything, at least with my camera and the way i focus.
    of course your camera, and your film holder, and tape-job might
    give you different results, but it might be a useful experiment for you ...
    considering the cost is sheets of paper and some masking tape.

    good luck !

    ps. feel free to look in my gallery and do a search under "laverne" or series d to see some photos ...
    no disrespect intended to the folks who have posted to this thread, they are all know their stuff ...
    but often time on discussion boards people talk and talk and talk, but they have never done anything they say they have
    and they are just repeating and repeating and repeating what others have repeated to them & i don't want to come off as one of them.

    jnanian,
    The .010 or so difference in film plane position between standard and Graflex film holders will not have much difference on images shot at small apertures but will on images shot at wide apertures. You may have gotten your taped on holders close to the actual film plane of the camera. TXP (triX 320) in 4x5 sheet is .007 inch thick. T Max in 120 is .0045 inch thick.

    http://www.flickr.com/photos/thirteenthumbs the 3A Graflex I made a new shutter curtain and modified the transport to use 120 film; the 3x4 RB Auto I made a new shutter curtain and an adapter to use standard 120 RFH.

    beautiful stuff shutterfinger!
    i also have a 3A, but the shutter is kind of wonky
    so i use a lens cap and paper negatives
    not as high tech as yours, but its OK for now ...

    you are probably right, maybe i got lucky !
    ( with the film plane ) ... i did throw salt over my shoulder
    and find a 4 leaf clover before i did the taping .. if i would only be so lucky
    with my power ball jackpot picks

    thanks for the link!

    jnanian,
    you may find this post of mine useful. It's the camera I put the shutter curtain in and modified for 120 film.

    Adapting a Graphic Film Pack Adapter as a focusing panel for a Graflex back

    I have a 2x3 Miniature Speed Graphic with the rare Graflex back, but no ground glass focusing panel. So I took a Graphic film adapter and taped a ground glass inside it were the sheet film would normally sit. Then I found a Suydam 120 roll film holder for Graflex backs. I shot a few pics last fall with this setup to check focus and it appears to be ok. The film plane and ground glass are in the same place. The Film pack adapter was easy to find. The Suydam roll film holder not so easy to find.

    Never seen a baby Graphic with a Graflex back... I own the only 4x5 Pacemaker I've ever seen with one . It's pretty well documented that it was an option, but you just don't see them.



    It was purchased new in 1956, per the original receipt.



    One of these days I'm going to pick up a bag mag for it.

    Receipt notwithstanding, the picture you posted looks very much like a Graflok back. It has too many sliders to be a Graflex back. Could you have posted the wrong picture?

    I'll grant you that it doesn't have the Graflok back's groove (like my Graphics') or Graflex back's ridge (like my RB's) at the right end of the gate.

    Nope...it's definitely a Graflex . The sliders don't have the "wedges" a Graflok has, and the focus panel is retained by them. At first glance it does look very much like a Graflok...but if you look at the focus panel, it's completely different from a Graflok--it doesn't have the spring bars you depress to remove it, it's just completely plain.



    But yea...unless you do a double take, it does look like a Graflok.
