Your lens likely has a Canon FD mount. The reasons are as follows: It has a breech mount. Canon FL/FD lenses are among the most well-known breech-mount lenses. The location of the linkages matches those on Canon FD mount lenses. Note there are two "pins" on the FD mount. One to "auto" control the aperture. The other to communicate the aperture position for ...

It is likely a Canon FL mount. If you are looking for an adapter, it is compatible with the Canon FD mount using stop-down metering. See Evolution of the Canon FD Mount. If you'd like, you can measure the mount diameter to compare with a list of lens mounts (alphabetical, by-register, Wikipedia).

I agree with Dave @HeritageCameras that this lens likely has a Canon FL mount. The reasons are as follows: It has a breech mount. Canon FL/FD lenses are among the most well-known breech-mount lenses. The location of the pin matches that of Canon FL mount lenses. (Circled in green.) The lens has screws that match those on known Canon FL/FD breech mounts. (...

This is an old thread, but if anyone's still interested I think that lens is in Canon FL fitting. This used the same breech lock mount as FD, with auto diaphragm but without all the meter coupling features. It was used on cameras such as the Canon FT and Pellix, while the lenses can also be fitted to many FD SLRs for stopped down metering. Dave, HCL

What it isn't: It is not a bayonet mount, which is far more common, but rather a breech lock mount. The bayonet lugs would have been on the camera side of the connection between lens and camera. It is not a normal example of either of the two most common breech-lock mounts: The Canon FD mount or the Canon FL mount that preceded it. The pin extends further ...

What is the exact model of your particular Tair-3 lens? There were several modifications of the lens which were made by at least three different factories. Some lens versions had m39 or m42 mounts, some versions (Tair-3A) had an A-type rear mount adaptable to either m39, m42 or Nikon-F via original interchangeable rings, and some were made specifically for ...
