My Componon 50/4 has identical threads for front and rear elements, so when going past 1:1 I can reverse the elements.

The Nikon BR-15 ring adapts M39 to Nikon F and adds 6.8mm extension.
Thanks! I don't seem to be able to find it for sale anywhere.

Just an info tidbit, longer focal length EL lenses are able to focus to infinity on a bellows unit. Many EL lenses are symmetrical and thus reversing them does not always improve their results.

It’s been discontinued for some time. This looks to be about the same:

I have a BR-15, and also a FotodioX M39 to Nikon F adapter for Visoflex lenses, 45.3mm long. I don’t see it listed now, though. Their adapters are pretty well made.

My Nikkor EL 135mm f/5.6 with the PB-6 bellow can focus pass infinity. My Rondenstock 105mm f/5.6 can focus to about 30ft.

Same with my 150/5.6 EL Nikkor.
I've seen 150 EL Nikkors in M39
mount but mine has a fine thread
flange arrangement with identical
threads on both ends of the lens.

Get an adapter M39 as it is threaded for most enlarger lenses.
Mount it on your bellows.
Mount the bellows on your camera and you are ready to go.
Very simple.
Some enlarger lenses might not be M39, unusual though and will need more effort to mount on a bellows.
I use the Canon Auto Bellows with the Adapter A which is M39 then put the FD to EF adapter on the back of the bellows and mount to my EOS camera. The meter will work just fine.
Then go have fun. A tripod is recommended.

You need:
An enlarger lens
An enlarger lens board adapter to mount the lens on the bellows (often a 32.5mm (Schneider) or 39mm (others) threaded, circular plate to hold the threaded lens, or a plate with a hole on it that requires a retaining ring on the back side). This can be a T-Adapter if the bellows has T-Adapter connectivity on both ends.
Bellows on a rail with a front control slider and a rear control slider.
Camera to bellows adapter for your camera mount. Sometimes this is a T-adapter.
Magnification is primarily via the front bellows. Focus is by moving the camera relative to the back of the lens. These actions interact, so work on a support of some sort (copy stand, film duplicator, tripod, etc.).

(Add on... Fotodiox makes bellows that fit Nikon F and Canon EOS bodies. They also make 39mm adapters to fit Nikon F and Canon EOS mount front plates on those bellows. So you should be able to fit one of those bellows together with your enlarger lens, if it has a 39mm (by 1mm thread pitch) male screw thread.

Maybe I should convert my "parts" Beseler 23CII to a copy stand. I could then use my enlarger lenses (50mm Nikkor to 150mm Schneider).

I used to copy my negatives and slides by remove the dichroic lamp house from my Beseler CB-7 put it on the baseboard upside down. Put the negatrans on top. Mount the camera with bellow and the enlarging lens on the column. It worked out well.

Earlier I mentioned about using a bellows with an enlarger lens attached to my camera. The lens is mounted using the Converter A designed for the F39 Leica threaded lenses including enlarger lenses.
Here is the photo of the actual set up. It works very well.
