many websites have the info... but www.billswelderrepair.com has the info on their site, too. Click on engine drive welders and scroll down the right hand side of the screen. there is a place to "click" on for Lincoln sa 200 serial #s
you can find it based on the s/n of the machine, and i think that info is on Bills site, i saw it just the other day, and can't remember right now, but will find it again and post.
