For Christmas, my mother in law gave me a book (which I had ordered)
called the Ultimate Asahi Pentax Screw Mount Book. It covers all the
screwmount cameras and lenses and is a very interesting read.
In the book, the author mentioned the Alpa maintained an inventory of
Takumar lenses and sold them as "Multi-Coated Auto-Alpa Lens". Here is
evidence of that.http://www.alpareflex.com/Lenses/Ashai_19_50.htm Bob Rapp
