Lens identification
Identifying a lens by only its focal lenght is impossible.
The words Planar or Sonnar do not help either.
A lens number may give an indication of what series a lens belongs to.
A description like 80/2.8 Planar still opens chances for seven! different lenses with two different bayonets i.e. B 50 and B 60.
If you are sure it is 60 mm for your lenses you have CF or CFi lenses.

This is the lens that I did buy.
It has 60 in the lens cap as I've just fitted the one from my 80mm on the back of what you just said and it fits!
Still quite unsure about the front focusing ring though.
Thanks

That lens has a B60 front bajonet. I have an identical lens.
Typically a seller who has no f* clue about what he is selling. Macro function... nonsense.
The front focusing ring is used to preselect a focusing range, it sets the floating lens elements (FLE) for optimal image quality. Subsequently you focus on our subject with the focusing ring closest to the camera body.
