Nikkor P.C. 10.5 cm lens -- mystery mount

Can anyone tell me what lens mount this is? I was under the impression that this rangefinder lens was only made for Leica screw mount and Nikon S mount. I am only familiar with the mount for Leica screw lenses. Thanks!!

Looks like a LTM lens with a LTM to Leica M adapter.

Mystery solved! Thank you. I didn't realize the lens had an M mount adapter attached to it.
