I bought a Panagor 100mm f2.8 and was told that is was m42 mount. It turns out is has another mount.
Can anyone tell by the picture what mount this one have ?

Pentax k and it's a 90mm lens Wink

You will like this mount, no hassle with m42 lenses being upside/down when mounted Very Happy

Pentax PK - or possibly Ricoh PK. It's exactly the same mount but Ricoh sometimes have that extra bit on the shroud at the back of the lens, the black bit that is sticking up in the first picture. If you are using Ricoh lenses on a Pentax digital then that part needs to be cut off.
I'm not sure about Pentax film cameras though.
On some lenses the complete shroud is easily removable so it's easy to cut the extra bit off, and it does no harm at all.

Yes, Pentax k mount is often referred to PK-mount as a short term (Pentax K-mount). And Ricoh as R-K-mount Wink

A couple of Ricoh / Vivitars I have are marked on the mount flange 'P/K-A R-P/K' and I've had to trim the shroud on both. But none of the Vivitar lenses for Pentax PK have any markings indicating the mount.
