I jotted down the number on a plate on the frame, it was
4177962. I figure he must have thought the 79 was the year, but I think it
looked more likely a 62.

There is no date coding in Case serial numbers. It is only a
sequential number, telling only that tractors position on the line.
Depending on the year, and if Case decided to start a new sequence at
the first of the year, it might jump by as many as 10000 from the last
unit of one year to the first of the next. The only way to find what
year it was is to contact Case. THe jumps in number don't mean
anything, and did not happen every year.
