1956 was the last year that Frankford Arsenal manufactured Cal .30 International Match ammunition. Lot FA 2165 is the one most commonly found in collections. It consisted of Sub-lots A-Z, AA and BB. Headstamped FA 56.
One additional lot, FA 2166, was also manufactured in a lesser quantity. I have been trying to document the Sub-lots of 2166. So far I have found 5, A thru E. If any of you have a carton of Lot 2166 please contact me or post the information here. Thanks.
