Is there an adapter for a Vivitar lens 28mm?

[armbone]

Hello colleagues.
I just bought a 28mm Wide angle Vivitar lens and I want to use it on my GH1.
I have a FD adapter that works fine with my canon 24mm and a Y/C that works perfectly with my Yashica lens.
Please, let me know if there are adapters out there to fit my Vivitar.
Thank you guys!

Is it an actual Vivitar T mount?IMGP1114vvtr.jpg (looks similar to M42 screw mount)
Otherwise here's a link to serials with corresponding mounts:

(not complete, but a start...)

I hope it's clear.

ok it's a 24mm (not 28). Could be Pentax K mount. Is there a marking "P/K" on the mount's face itself, or on the body?

Hello,
Thank you very much for responding!
I see a PK-A/R-PK96070586.
Is it a Pentax?
And you are right, in my rush to get the information, I missed the 4 and typed an "8", it is indeed a 24mm.
Thank you
Let me know which adapter should I get.

I thank you all for your input.
I found what I was looking for thanks to you all.
I thought that the FD converter I had for the Canon lens would fit the Vivitar.
Little I knew that it was a PK mount.
I will get it from the site you suggested!

Thank you again!
