No, sorry, most certainly K-mount and not Mamiya-Sekor. If I take the OP's photo and overlay it at the same scale with a known K-mount image they align perfectly.

Bayonet, aperture lever and even mount lock indent aligns exactly.

Thanks!

It is definitely K mount.
I used to have Sigma with ball bearings , it worked well on all my Pentax DSLR's.
