It is possible to find them: I have one which came with an ES, although it is otherwise missing a few bits! I also have an SMC Takumar 50/1.4 (which came with a Spotmatic) which is in superb condition but I am not sure whether it is of the series which tends to yellow. Previous discussion of this point tended to conclude that the yellowing is in the glass itself, and therefore could probably not be reversed. You are probably right on the last point, but I cannot confirm absolutely - makes sense though.
