if you have one, you could always put a sheet of paper in it ..

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.

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!
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
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've seen another Graflex with sliders Top and Bottom, may have been a Super D I serviced a while back. The 2 slider Graflex sliders do not have the tilt of the Graflok. I think it was a late production change possibly 1945 or 1946.
