Does anyone have any specific information on the correct dimensions for the
lens boards for the various models and sizes of Speed/Crown Graphic cameras
or know of a website where such information could be found?

If it matters, I'm specifically interested in the Pacemaker 2-1/4 x 3-1/4
Graphic now but information on the other models is desirable too.

www.Graphlex.org was of no help in this matter.

TIA
Norm
