·Hello all. I have been searching everywhere to try and narrow the production date window down but am not having very good luck with it so my question is has anyone gotten an extract of the archives that shows their production date? I know from an article i read that a 39,923,8xx serial puts it around mid to late 1977 and mine is 39,923,9xx so i would think it would be somewhere around there but all the charts and lookups ive tried are all over the place between 1976 and 1980 and i was just hoping maybe somebody with a serial that was pretty close to mine had gotten an extract with a production date to help me narrow it down. Anyways i just figured id ask and hope for the best. Any help would be very greatly appreciated. Everybody have a good day.
