After some googling, I found someone using a 240mm Sironar (which is a copal 3) on a Crown Graphic. Did not mention if the RF worked, but at least it looks like they can handle a lens of that size and FL.
Thanks, but I probably do not want to get into any customization.I’m pretty sure you could have a 240mm lens cammed to a Linhof Technika (ideally V or Master, but a IV would work, and there are a few independent technicians who will grind cams for the Tech III), but it can be an expensive proposition.

I do not know much about large format rangefinders. If it is something easy, I might try it. I probably have too many cameras already.
There are accessory rangefinders from the day that fit into a hot shoe or use a similar bracket that mounts onto the camera or can be used handheld.

That might be me. I have that lens on a Crown Graphic, but I don't use the rangefinder with it. The arm for the Kalart doesn't come out nearly as far as would be required. The front standard is pulled way out to near the end of the rails. For portraits, I need maximum extension and can get about 5 feet from my subject for a half length view, as in the example here. I used theground glass, and my subject had the chair to maintain distance, and I think I used f16. I think the Sironar is somewhat telecentric too, IIRC. Because it focuses at portrait distance does not guarantee your Nikkor 240mm will. If you tell me the flange to focal plane distance of your Nikkor when focused on a light bulb about 5 feet away, I can see if the Crown would permit that.After some googling, I found someone using a 240mm Sironar (which is a copal 3) on a Crown Graphic.

Donald, there's only Pacemaker Crown Graphic. All Crown Graphics are Pacemaker Graphics. They were made in three sizes, for 2.25" x 3.25", 3.25" x 4.25", and 4" x 5". Is that what you meant to say?
The 4x5 Crown Graphic's maximum extension is 12.5". The 4x5 Pacemaker Speed Graphic's maximum extension is 12.75". This from Graphic Graflex Photography, 10th edition. Not much of a difference.

The Crown and Speed use the same bellows in 4x5 format. The film plane is at the rear of the camera body. The Speed has a deeper body due to the focal plane shutter. The focal plane shutter curtain rollers are about 3/4 inch in diameter with no more than 1/8 inch clearance between the roller and bellows attach point of the body.This small difference is surprising! I briefly owned both a Crown and a Speed 4x5 and the difference in the depth of the box is about a full inch. So they must be attaching the back of the bellows quite close to the back of the box in the Speed; maybe some of the shutter assembly is actually outside of and forward of the bellows attachment point; I no longer own one to look at how it's put together.
Also worth noting that the Crown above is a Pacemaker model. Different models of Speed and Crown had different bellows length, IIRC, and in the same model, the extra depth of the focal plane shutter gives the Speed a little advantage on closest focus.
RF are useless for practical use in large format cameras unless the diaphragm is step down a lot (f/16 or so).
