Below is a photo of a M2A1 ammo box (can), considered the “new style” (short sides on the lid) produced by S.C.F (Standard Container Company(?) and is stamped S.C.F. on the hinged end of the can. This can is early S.C.F. manufacture since it is not stamped with the last 2 digits of the year of manufacture as found on latter S.C.F. M2A1 cans.
LC 60 -143 is the lot number which is the lot designation established by MIL STD 1168 (in use from 1949 to 1975). LC = Lake City, 60 = interfix number and 143 = serial number of the lot. In 1975 the lot designation format was completely changed with adoption MIL STD 1168A.
The M200 designation for the 5.56x45mm blank was approved in 1968.
So the time range for this can is potentially 1968 to 1975.
Can anyone provide a date for this can based upon the lot designation?
When was the 'new style" M2A1 can by S.C.F. adopted?
Any help, corrections, discussion are appreciated.
