I didn't measure the width of the most forward flange thread
Thanks Dan, Looks like an Ilex no. #5 hole at 85.47mm would fit properly on the most posterior smooth back of the lens width at 84.5mm. I was a bit confused seeing the two flanges - thought perhaps there was something way beyond my figuring out....
I've been a bit distracted by water coming through the ceiling around my skylight in my studio - placing multiple plastic crates to catch the rain that is almost horizontal hit on my house with high winds. Sorry if I didn't present clearly on the lens.
Brad,
Is the front-most flange connected to the lens aperture adjustment?
As these lenses were also used for photo-reproduction work, sometimes they mounted an extension onto the aperture flange to use as a pointer on a large dispaly of aperture.
Seen this aperture flange on a couple of Apo-Nikkors I have handled in the past...
Would explain the two flanges.
Hope that helps,
Len
30 inch and 40 inch Rodenstock Apo Ronars by Nokton48, on Flickr
On the right, my 30 inch 760mm F14 Rodenstock Apo Ronar which I have owned for decades, great for 8x10 product photography. I have a Norma forward mounted lensboard in my Norma Lensboard box which fits it precisely. My new addition left, is the 40 inch 1000mm F16 Rodenstock Apo Ronar, this is the exact lens type shown in Reinhart Wolfe's book "Castles in Spain" which I have owned for decades. Also his book "Villas of the Venito" and the famous book "New York" I have several copies. Andy Warhol interviewed Mr. Wolf and it's a great read Mr. Wolfe exhibited in 1975 (I believe) at Photokina in Germany. So his gigantic mural sized color photos were seen by multitudes of Photokina visitors at the time. Rebuilding this very camera is a fun unique project. The new lens came from a dealer in the UK at a good price. I will be contacting SK Grimes to build front and rear lens flanges, which I will attach to original Norma boards precisely. I wish to use the lens for 8x10 B&W telescopic photography. Wolfe photographed local Architecture in the Deep South USA which I think are the most beautiful myself.

1000mm F16 Apo Ronar. Hollywood Gaffer Tape (not the cheap crap) holds together this prototype. Norma Standards are buggered (no microfocus on either of these) so here they morph into something useful to me. From Norma Junk to my Treasure

Sinar Norma Special Bellows 1 by Nokton48, on Flickr
I sent Keith at Custom Bellows, a Norma 5x7 Bellows Frame, and an 8x10 Norma Bellows Frame. Also pictures of the "Sinar Norma Special Bellows" right out of the Norma catalog. He made this "Special Bellows" for me, I have never seen one in all my years of searching. Also shown on the above camera. Keith sent me this digiphoto, right before shipment.

Yes! I have that lens now. Here I am working on assembling the same rig used by Mr. Wolf! I need front and back screw-in rings, the rear lens mount will need to be forward mounted, to work with my Norma Shutters. SK Grimes can build these pieces on their CNC machines.
