need help IDing a lens

[dreamingartemis]

Hi,
Recently a friend of mine bought a whole Mamiya RZ set (body and lenses together in a hard case) from a lady who was selling off her ex-husband's medium format gear and while my friend is a pro at medium format, there was a lens he couldn't figure out. I figure I could help him find out more about by asking the great info database that is APUG . A little bit about what we do know, it seems to be a fisheye of someshort and it's made by Rodenstock though it started seem to have a mamiya mount (we suspect an adaptor is needed). What strikes me as odd is that the lens was part of this collection even though there is no apparent way to mount it. Here are some photos of it

It's a large format lens, not an RZ one. It's a pretty nice "normal" lens for 4x5/5x7" large format.

but what kind of mount is it meant for? Sorry I'm not at all familiar with large format stuff, I'm actually more 35mm but my friend runs a studio.

Looks to me like a Rodenstock Sironar large format lens in shutter. Not sure of age - I believe the Sironar was replaced by the Sironar-N. My guess is 70s vintage. Looks in good condition. Not a particularly rare lens, but a good one. Not sure there's Mamiya mount involved; I suspect it just got mixed up with the Mamiya gear.

Like most large format lenses, it doesn't have an proprietary mount. It's in a Copal #1 shutter and will mount to any lens board with the correct sized hole. The rear cell is unscrewed, then the shutter retaining ring is unscrewed, the shutter (with front lens cell) is placed on the drilled lens board, the retaining ring is screwed on (fixing the shutter/lens to the board), and then the rear lens cell is screwed in.
