Hi I have a russian SKS that I bought back when I didn't now much about sks's. How do I Id this eg: Date manuf. arsonal. It's in nice shape apart from having a gouge taken of the front end of the laminated stock. Paid 125$ for it 4 years ago. BTW is a ak sling the same as a sks sling, canvas with "s" shaped leather atachments. Thanks RF
