Matthew - it is kinsten stuff I had that I
found to have lost a lot of sensitivity and
a little bit of contrast when many year out
of date.

However sometimes when I order the Kinsten
boards from Perth they come in different
shades depending on batch. They range from
drab green to bright green. So there may
even be marked difference in the "past used
by" performance in the one brand.
