At this time, no coherent correlation exists between Serial Number, model number and year of manufacture.
If the amplifier chassis is removed from the cabinet, you can usually find a handwritten label or date in grease pencil somewhere on the inside or on the outside of the side panels.
The 212HD-130 was replaced by the 212HD-150 sometime in late 1979 or early 1980 (according to the information I have). It can be no older than 1974.
