| I believe a #10, but good luck, that particular number is hard to find. |

I use a #14 mask for my 22 (6x6) Graphic Back. It is 1.14cm square. The width would only have to be filed out by 0.19cm to work with a 6x7 back. That is for a 135mm lens on my 4x5 Crown, a great combo!
My 23 (6x9cm) back uses a #8, It has spikes that could be filed a little bit for a 7mm measurement.

AFAIK, there were no masks made for the 6x7 format, just 6x6 & 6x9.
See the following link to Graflex.org for the mask chart:

I'm familar with that chart in your indicated link, but I was basing my answer from information found in a 1973 Graflex catalog that I had when I left retail sales back in the early 70's.
On page 31 there is a chart for the Catalog #9105 Viewfinder Masks and #9105-10 is listed as a # 10 mask that can be used for:
2 1/4 x 2 3/4 (127-138mm lens)
2 1/4 x 3 1/4 (129-152mm lens)
3 1/4 x 4 1/4 (179-203mm lens)
4 x 5 (217-241mm lens)
Also for those interested, the Wide Angle (WA) Viewfinder Adapter seen on e*** from time to time is Catalog #3060 and shows the field of view for the 90mm WA lens, I don't remember the retail price when I sold them, but nowadays they run about 25-50 USD.
If Graflex.org wishes I can supply a scan of the chart I refer to as it may be more accurate than some charts I have seen. |
