The steel-cased 5"/54 and the new lot numbering system came well after my time but I know enough about them to make some uneducated observations.
MCA89F001-001, NIV86K001-033, and NOR89C001-017 are ammunition lot numbers that identify the manufacturer, year, month, interfix number and lot number. As Western said, NIV is the old designation for Norris Industries which is now NOR. MCA is McDonald Mfg. Co. His case was made in 1986 and either reloaded or refurbished in 1989.
I believe that the lot number, combined with the first series of letters and numbers is the new system replacing the old ALN (Ammunition Lot Number) and FSN (Federal Stock Number). Probably related to the new-fangled DID (Data Item Description) and ADC (Ammunition Data Card) designations. I don’t know what exactly ADL signifies but I’d guess Ammunition Data Lot ??? Or some code for type class, etc.??
BTW, in real life, the lowly Gunners Mate knew the meaning of all those numbers and letters on both the cases and projectiles but seldom referred to them or used them.
Just my SWAG. Some of you other GMs please bail me out.
