Colt date of manufacture

[Oddnews SASS# 24779]

Can anyone give me a good online source for serial numbers and dates for late Colt SAA manufacture? I just acquired SAA S446XXXA and I'm trying to determine its year of manufacture. I'm not willing to "letter" a non-collector gun such as this one, I'm just curious as to the year it was made.

Thank in advance for any and all help.
