I purchased a Husqvarna 455 Rancher on 9/17/08 from Tractor Supply Company and a Stihl MS 025 on 2/28/95 from my local Ace Hardware and both were stolen sometime between 11/22/08 and 12/4/08 from my home in Columbia, TN. The Serial number of the Husqvarna is 965 03 02-00 08 0800323 which I found on a sticker on the box which I still had since it was only a couple months old. Possibly only the end of the Husky number is the actual Serial #. The Serial number of the Stihl is 230106635 and I actually got that number by e-mailing Stihl to see if they had my purchase of that saw on record and luckily they did. So it's worth an e-mail to Stihl if you don't know the Serial # of a piece of their equipment.
