I have a number of viewfinder masks but I didn't see any numbers on them.

1. How do you figure out which masks you have?

I use this reference to match my lens to a mask:

https://www.graflex.org/speed-graphic/viewfinder-masks.html

I also found a list of masks for the roll film holders (RFH) here:

2. So for a 101mm lens with a 2 1/4 x 3 1/4 rh8 back a 9105-2 mask is listed but the first ref does not list a mask for the 101mm lens. Does that mean that one is not needed?

3. Is the 9105-2 the same mask as the #2 mask listed in the first reference?

Thanks!

I have been looking for a 9105-9 mask. Do you have one to sell?

Tony, I'd go with the printed mask data you posted from the Graflex company literature, in preference to the info from that page on this site. On my no. 2 mask, the number "2" is stamped into the metal on the upper back inside (facing the finder optics) edge of the mask, under the flange along the top of the mask. I don't know what it means when the number is missing: after-market item, factory omission, or what?

Henry,

Thanks for the info. Using a magnifier I was able to find the numbers that are stamped in my masks. Turns out I had one #4 and two #2 masks.

Sirius Glass, no #9. Sorry!

There's a #9 on ebay. $s5 seems high.

Apparently, Graflex didn't distinguish between 6x7 and 6x9 formats in their mask production. My no. 2 mask is proportioned for 6x9, but I always shoot 6x7. Just one more reason that I've called the optical finder only an approximation of what the film sees.
