I wanted to add that even though there are ANSI specifications for
14X17 holders many cameras of this size were built before the
specifications were established so it is important even here to
verify that the dimensions of the holders and camera back match. It
is often possible to modify the back to accept holders but sometimes
this can be quite difficult.
Anyone interested in 14X17 holders should contact me off-list as I
have a couple for sale (made to non-ANSI specifications for a very
old pre-ANSI standard camera).
