The serial number of one I know was built prior to its purchase on Nov 2, 1990 is 22248322. Since this one is 8 and yours is 9 digits, I'd say yours is considerably later. I also have 026's with the serial numbers 228874912 and 241159621 one being metal tag and the latter being plastic tag. That new 026 cost $378.50 out the door with an 18' bar and a free case. I still use it.

That was a lot of money for a 50cc saw 25 plus years ago but a very inexpensive saw per piece of wood cut. A quality purchase will often prove to be a better value in the long run. That comes out to less than $15 per year of ownership and it does what it needs to do whenever I need it.
