Les Newcomer pointed out that we had a missing "D" and an extraneous "N" in the Graflex manufacturing code table <a href="http://graflex.org/speed-graphic/manufacturing-code.html"</a>here</a>. I've updated it, so if you dated your camera based on this code before, please re-do it.

Thanks to Les, and sorry for the confusion.

Leigh.

Leigh,

It's still wrong! Letter "I" was not used, according to the text; this new chart uses "I" and omits "H"!!
