can't find my colt book
 

would some one look up Ser# 20884NM and let me know the Manufacture date. I'm thinking it's 1967... thanks.

Government National Match Reworks â?? These pistols were assembled by government armorers with all parts marked "NM" and had a parkerized finish. Most will have "S.A." markings for Springfield Armory. Colt: S/N (approx.) 20,000 to 83,856 = Jan. 1913 to Aug. 19, 1913. (This doesn't sound right, does it?) Perhaps you need to provide a littel more information, I just made a lot of assumptions: (1) It is a government model .45? It must be a "national match"? etc. Suggestion: You can do a www.google.com search and there are all kinds of places where you can look this up, etc. Hope this helps.

Thanks. It's a pre-series 70 National Match 1911a1
