In early years ABU mfg around 50-60,000 reels BEFORE they serialized them, usually only with lot numbers so they could track inventory. They began six digit codes in early fifties which have been revised at least four times and may mean different things. Code is stamped on bottom of reel foot, There will be 6 digits on the reel foot. An example might be 080400. Reading the numbers from left to right......The first two numbers of "08" are for the month of (August).....The third digit will always be a "0" indicating the number "6" for the 1960s decade. The fourth digit in this example "4" is the actual year of that decade, 1964. The last two numbers "00" would reflect the number of revisions made to the reel which are none in this example. Another example might be 120501. (12) December (05) 1965 (01) revisions. How you read a lot number changed in 1970 with the second and third type date code. Now, the actual year "70" was used. Second type: MMYYXX....month, actual year, revision. 1970~mid to late 72. Third type: YYMMXX....year, month, revision. Late 1972 into the 1980s. (most common type).
Those who would give up constitutional freedoms to elected officials in exchange for a false sense of security, deserve neither freedom or security.
