The first place I went to find out what the code might mean was vintage-trek.com. Alas, it appears that the Date Code key had been lost, according to a correspondent quoted there.
But I'm wondering...could the '7' be for the year 1977, then the 'K' for the month November?
Goodness knows what the first character--either an O or a zero, might mean...
Anyone have further anecdotal 411 to add?
