Interesting.
Maybe in Japan they never heard the howls of indignance and general uproar about Pentax calling these Takumars.
I remember a few of these coming through a shop where I worked back in the 80's, as I recall, the zooms were dreadful, (Ran across one this year, and it was practically falling apart, even, ) but this actually seems pretty well made. But, it was pretty slim pickings last night on Ebay when I peeked, and someone was trying to get that kind of money for one of these. And the M's were crazy.
