From your description, all my 50 mm Sears lenses (2.0, 1.7, 1.4) are all Chinons, which I can believe because these Sears lenses are all over performers. I also have a Sears 135 mm f 2.8 which sports the typical Chinon colors, and it is also an over performer, unbelievably sharp with excellent out of focus blur, amazing for what today is a $15 lens on eBay. (I also have 50 & 135 auto Sears in like new condition for Canon mint & if anyone is interested drop me a private message and you can have them for a song.)
