Hi Southernshooter.....welcome to TFF.
I don't know of any published list that matches serial #s to particular models of the SKS.
However, there is a site that's dedicated entirely to the Simonov firearms, http://www.simonov.net/sitemap.htm
This page lists all of the various types of SKS's: http://www.simonov.net/ubertypes.htm
You should be able to the find the answers to your questions there.
