Alpa had their own bayonet mount. Late in the Alpa company's life they bought a Chinon Mematron body, (I believe, but it could have been something
else), with a more "Alpa like" Prism housing and re-badged it with the Alpa name. It used M42 mount lenses. The two other links were just
Japanese manufacturers lenses in the Alpa bayonet mount. I knew that Chinon supplied them some lenses, I didn't know that Pentax, (Asahi), also
produced for them as well.
I questioned the salesman, this lens has a screw mount, not Alpa mount. It's well the lens manufactured by Chinon. Michel
