FWIW, almost all headstamps, and all U.S. GI headstamps, are oriented so that they are read in one direction. So if you can read the "F" and "A", the date is just what you see.
Just a note that Frankford Arsenal was the U.S. Army's major ammunition factory; it was never a small arms manufacturer. One statistic is interesting. From late 1941 to late 1945, Frankford Arsenal produced 1.5 million rounds of .30 caliber ammunition - a day.
