The lack of variations could indicate a single production run, with lots of parts in storage. Variations only are introduced when a new production run is started, usually after the stocks have been sold. So perhaps Record derailleurs were made only once, in 1962? Then they sold the remaining stocks, and when they were getting low, they introduced the NR as the next iteration?
Of course, that is just speculation. That said, I would be very
surprised if Campagnolo had _produced_ any Record derailleurs after
1967. The fact that they were seen on OEM bikes indicates that they
were sold at a discount to get rid of existing stocks.

As pointed out earlier, "available" does not mean "in production." It's not like Campagnolo had three assembly lines, one making GS, one Record and one NR derailleurs. They had a warehouse, with a shelf for GS, one for Record, and one for NR derailleurs.
The Alex Singer shop had their cam-actuated brakes in stock for decades. They had 500 sets made in the late 1940s, then the Mafac brakes came out, and the bike market collapsed, so there was little demand for these brakes. You can find them on 1960s bikes, and you might think that they still were "making" them, but in fact, they were just using up 15-year-old stocks. So the brakes remained in the program until they were sold out...
