I see the notes about determining age of the WSM, but I have a OTG and Performer which are both stamped with the letter "R".  The OTG was purchased around 07/2000 (wedding present from the wife).  So it might be a 1999 or 2000 model, but it could be older.  Does anybody have this info??     
BTW - cleaned them both today, they look so nice.
The Simpson model was out about the same time, I almost bought one.
