I just bought a used set with a similar badge.
I found an equivalent on a thread about Pearl Export badges on the Pearl forum, and a poster says his is from 1999.
Mine is dark blue (the Pearl "Deep Blue"?) and same rectangular badge, no serial number.
Kit as I found it is 22x16 (metal), 10 x7, 12x8, 14x10, with "Steel Shell Mirror Chrome" snare.
There is a PDF doc called "Export Time Line" that someone put together, and it shows each model year, including, shell style, factory colors.
