Maybe somebody here will remember, about a year ago I posted a website that would provide the date of MFG on a US military firearm based on the SN. I've got to hang around here another hour or so, maybe I can find it. Price is out of my range and I'm a mongrel shooter guy anyway but it may not be unrealistic.

Found it!The site
http://oldguns.net on the very bottom of the main page will tell you the year of
manufacture of US military firearms by entering the serial number. Click on the MAIN PAGE
on the blue screen then scroll all the way down. Don't do it from here cause I couldn't get
back without completely closing the system but that might be my problem.
