Does anyone know anything about LCAAP lot numbers?
LC was assigned several blocks of 5-digit lot numbers during WWII, such as LC 12125.
In January 1970 the numbering system was revised by using a prefix number followed by a lot number, such as LC 20-26 .
Sometime around 1978 or 1979 they began using much longer lot numbers, such as LC 79K130-007.
Anybody out there know how to decipher the latest numbers???
