Magnificent lens. Do you know . . can you say . . whether this is a 1/2" lens or is it a 2/3" lens?
If a 2/3" lens then I agree it is B mount. I personally would never attempt to convert such a beautiful lens to m42. I would, instead, just purchase a B mount adapter.
If lens is a 1/2" lens things become more complicated. While the mount (of such lenses) is very similar in appearance to B mount, it is not the same and the flange focal distance is different.
Uncertainty regarding mount differences can be resolved by measuring the mount locating pin diameter. Pin diameters of the two lenses are NOT the same.
Here, for whatever help it might be to you, is a link to a B mount adapter. I cannot promise, though, that this adapter, which is for 2/3" TV lenses, is the right one for your amazing lens:

Fascinating. Most any TV lens I've ever encountered would vignette wildly on FF. Your lens must be something outside my experience. TV lenses are a world unto themselves.
I do stand by my comments on the mount, though. Exception would be if you are able to convert the lens in a reversible manner. Then it would be OK . . in my view . . to convert the mount. |

I've converted the mount in M42 and this is not reversible... _________________ French lenses, what else ?
