Tnx Mark.

Here is why im asking this...

Recently a friend give me as a gift some "5 or 6 years old" rubber.
He is not sure the year, but seems the range is from 2001 to 2003.

The rubber is yellow sigly turning into orange (or brown), more
stronger and vivid color than the light pale yelow from recent SS'05
and SS'06. And for sure it is very different from the "yellow turning
green" from TAN 99.

Im wondering if its possible to know if it is 2001, or 2002 or 2003 by
the color. I post one photo, maybe that can help.

In photo you can see a 99 piece, a SS 06, a SS 05 and Oct 05
between them I placed 4 strips of this unknown year rubber.

Here is the image:

Thanks.

Ignacio.
