Good eye though man, you must have some decent search filters set up or get auto notified or something. You're always finding good stuff!
Tks. I (again) miscopied from my listings notebook on this beastie.
No filters or magic - I do a daily check of George Stragand's milsurp firearms site, from a desktop icon pointed to his SKS lists. Refreshed every 24hrs, searching "SKS", as well as other types that are listed under dozens of tabs for other milsurps. His site somehow collects listings from practically every major auction house on the web; also has Recently Sold and Available listings for every type and variant, going back 6+ months.
