Re: If I were to custom-make plate holders, would you buy them?

The beauty of having these made is that the process of changing the plate
opening isn't very intense or expensive. Making 5x7 or 4x5 openings in an
8x10 holder would be perfectly practical. I could probably engineer a
holder that would give you two 3.85 x 9.85 panoramic windows with a
specialized masking darkslide so you could load two dry plates in one holder
(you would just flip the darkslide around to expose the other frame after
you recomposed).

I was planning on making the quater plate size 3.25" x 4.25 inches which I
believe is historically accurate. I'm having trouble locking down the
precise dimensions for full plate. Based on my research, full plate is 6.5"
x 8.5". Can someone confirm this?
