The Alexandria City Council is composed of a Mayor and six Council members who are elected at-large for three-year terms. The Mayor, who is chosen on a separate ballot, presides over meetings of the Council and serves as the ceremonial head of government.
The first two or three letters (LL or LLL) were for the Manufacturer's Code. Each manufacturer had a unique code designation.The digits were the Lot's serial number. This was originally 4 or more digits long. Blocks of 4-digit Lot serial numbers were assigned to each manufacturing plant. The date of production of the lots (and the type and grade of ammunition and its packaging) was tracked by biannual supply bulletin rather than marked on the exterior packaging.
There was confusion at the start from a lack of rigid standards and oversight. Some contractors would use a serial number sequence for each type of ammunition they produced, meaning there would be lots of different ammunition types produced at different times that would have the same lot number. Others grouped ammunition of different types produced at the same time into the same block of lot numbers. This was sorted out by the end of World War Two when more oversight was possible.
The first part (NN) is the serial number, next the Manufacturer's 2 or 3 letter code, followed by a four digit number that indicates the two-digit month and two-digit year it was manufactured. For example, 123-JOP-0554 means it was Lot 123, made by Joliet Ordnance Plant (JOP) in May 1954.
For most of the 1960s there was a different system used for smoke grenades: NNN/N - Y/M - NNNN (there is no slash in the actual lot number; it is used here to divide the serial number information into sub-groups). For example, the lot number 1023-65-1234.
LL/NNNN was the Lot number; the letters (LL) are the Lot Interfix and the numbers (NNNN) are the Lot Sequence. The next block of letters are the three-letter Manufacturer's Code (MMM), followed by the two-digit year of production (YY). For example, AB1234HAW76 would be Lot AB1234, made or repacked by Naval Ammunition Depot Hawthorne (HAW) in 1976 (76).
1. Secondary parallel contouring axes, (e.g., the w-axis on horizontal boring mills or a secondary rotary axis the center line of which is parallel to the primary rotary axis) are not counted in the total number of contouring axes. Rotary axes need not rotate over 360°. A rotary axis can be driven by a linear device (e.g., a screw or a rack-and-pinion).
4. Foreign governments seeking to land state aircraft at U.S. military facilities located in a foreign territory do not require a DCN issued by the U.S. government; however, they do require a landing authorization number per paragraph B.5 below. 2b1af7f3a8
