Hey Dave.
Not sure what you mean by "flank".
Did you mean "flange"?
Just so ya know
A flange is attached to a lens board with screws. Then the lens barrel is attached to the flange.

RD Gray made what I've found to be very nice WA lenses in the 1880s-1890s. Their EXtreme Wide Angle is very nice. Sample shots in one of the links above.
thanks guys.
Louis, yes, that's what I meant.
is there anyway to mount this on a shutter?

Yea you could front mount to a shutter but why? This type of lens is best used stopped down so most times your exposure times will be 1-5 sec. You can just use your lens cap.
You could front mount the lens to a shutter like a Ilex #4 but you will need an adapter made as there are NO direct fits.
You could also use a Packard as a shutter option.
