I'm the proud owner of a Graphic View II. I was heavily influenced by the article here by Gerald Pierce. It made a lot of sense to complement my Crown Graphic to have more extension (for my Sironar 240mm lens) and movements. Everything seems to work fine. It came with three of the lens board adapters to take my lenses on Pacemaker boards. I plan to use it for still lifes and portraits. The serial number is 485049, stamped on the back of the front standard. Can someone with access to "the book" date it? I see a set of Crown View IIs starting 485150 from 1961-2 but don't see any listed on the coffsbiz site with an earlier date.

1961.
It should have a date code https://graflex.org/helpboard/viewtopic.php?t=3321

Thank you Charles. It's the same age as me. I don't see a date code anywhere, and the document you linked does not give a location for the code on Graphic Views. When I crank up the front standard, it reveals another number stamped on the back of the yoke, 25636, and a trailing symbol which looks like a capital O with something inside, perhaps a capital Greek theta.

25636 is likely a casting number.
