Hello everybody.
I just both a Super Graphic which don't have lens board and cam.
I want to use this camera whit a 210 mm / copal #1.

I find this lens board in a auction bud I don't understand what I have to do whith the "jumb nut"

Thanks for your help!

Description of the lens board:
This is a flat lens board for a 4x5 Speed or Crown Graflex camera. This is an original flat board. The shutter hole is 1 9/16" so this would take a Copal 1 shutter. Of course it is not threaded so you will need a jamb nut for your lens.

Hi. It sounds to me like they're telling you that, since the hole in the lens board is not threaded,(they usually are not) you insert your lens/shutter through the hole in the lens board and then secure it with a jamb nut. Also referred to as a retaining ring, you thread it onto the threads of the lens/shutter to secure it to the board. Fred.

Thanks for your help!

I'm afraid I have some more questions!
The lens board in a Speed Grahpic feet the size of a Super Graphic?
Do you know were I can get the retaining ring?

Frankly, I don't know the answer to these questions. Perhaps someone else can jump in here. All of my lenses came with the retaining rings. http://www.stephenshuart.com sells lens boards and can probably give you advice on the lensboard question. Fred.

Thanks Frank!
The url will help!
