The lever looks similar to a Pentax K mount, but the locking notch in the centre of one of the bayonet ears gives it away. I think it's a Konica lens.

This page on Rick's site is extremely useful:

Thanks Peter, I've looked at peter's page but that Konica lens is not easy to see Smile I've looked at ebay and I'm agree with you it's a Konica:
"This lens is for Konica AR (EE) mount bodies, such as the Autoreflex T, A, T3, A3, T4, TC, and Konica FS-1, FC-1, FT-1 motor, FP-1, TC-X, etc. "

Which version of the 28/2.5?

I can report that the Konica bayonet will mount on a Pentax body, but you get a semi-macro setup, as the Konica register distance is smaller. So there is a built in extension tube effect.

Why can I report this? Because I bought a "KA" mount Vivitar 200mm lens with the 'EE' mark on the aperture ring, thinking *doh* it was a K-A mount. Rolling Eyes Well the lens was cheap enough and my brother in law lent/gave me one of his Konicas.
