Nope, positive it's not a Nikon F-mount.
So your lens looks alot like a BNCR, PV, or Arri PL mount due to it's locking mechanisms, but all of those have 4 prongs at 90* intervals, while yours is three, at 120* intervals. Very interesting.
**My best guess is that is a B4 lens mount.

On "PV Mount" (from Wikipedia):
"The mount itself contains four pronged flanges, one of which contains a locating pin in the center."
If that is correct, then it looks like the mystery remains...What was your second guess?

Right, I ruled PV out along with PL and BNCR, because they are all four pronged.
*I edited my last post for clarity.
**My best guess is still the B4 lens mount.

Ryan,
I believe you may have nailed it with that best guess - there isn't anything I'm finding that makes me think it's NOT a B4 mount. Awesome.
Thanks

Haha not to question myself... but,
That is a great guess. I didn't think of considering his lens was made by cinema products which made the CP-16R. The lens mount I've read about for the CP16r was a C mount (it's not a C mount) or CP mount, which is described as a 'mini BNCR'. I don't know what the hell a mini BNCR is, but the regular BNCR is four pronged. CP mount is a good guess, albeit very very rare type of mount.
So I'd say it could be the unknown & mysterious CP mount or the B4 mount (which we know is three pronged).
I've personally worked with B4 lenses in the past, and this does look B4 to me. Have you taken this to cinematography.com? They work with this stuff more than I.

Yeah, he's right.
Here is a photo of a Cp-16r
Assuming it hasn't been converted to another mount, it is three pronged. Looks alot like B4, but they are probably only different by size, which I cannot tell looking at the photos.
The fact your lens was made by Cinema Products, I'm gonna have to settle with Bjingbar on this one.
It's a CP mount lens, only compatible with the CP-16r, according to the Professional Camera Man's Handbook, 4th edition.

Holy moly, is this my future?

That does make sense, as the mount is cinema products. No wonder it was a bear trying to trace it back. Still don't know too much about it ("very very rare" is right, I guess) but at least now I've got a starting point.

What did you need to know about it?
Do you actually have this lens physically? Because I have some questions for you about it.

Actually the camera was very popular in the early 70's before the introduction of the Arriflex SR cameras. It was easy to put the film in the magazine but to lace the magazine onto the camera was another thing.
Mainly used for newsreel and documentaries, a good workhorse and never gave me any troubles

Yeah, that film path is nuts on the CP-16. Never seen it in person, but was just looking at a diagram.
Ryan, I do have the lens right here in front of me. It came with an Arri, but obviously wasn't compatible.

What is the make and focal distance of that lens?

It's an Angenieux zoom lens, 9.5-57mm

Yep! Angenieux lenses were the makes for CP-16's. Cool. Did you know it was incompatible when you got it? Or did they not tell you?

It was thrown into the mix with an Arri package. More or less, the conversation went:
You ever seen one of these before?
Nope.
Well, it's yours if you want me to throw it in with the Arri. I have no use for it.
Sounds good.
And that is the legend of mystery lens.
