Lars,

I enjoyed your article very much. Lots of fascinating detail! I took notes :), and I'll follow up with some specific comments tomorrow.

For anyone who missed, here's the link to Lars Bergman's pdf again (plus added preview):

One comment, while it's fresh in my my mind. You wrote:
"Here it is clear that a radio receiver was on board, and also that they had two chronometers."

This is one of the clearest examples of a transitional era. A few decades earlier, multiple chronometers were the best choice —and not just two, maybe three or four, if they could be bought for a fair price. But now there's radio. Radio changes everything, and in a few years it will make chronometers far less important. If I have to sail for three weeks by chronometer alone, I want several excellent chronometer to serves as checks on each other. That's how it was a few decades earlier... But if I can get a radio time even once every few days, then a single chronometer may be all I need.

More later.
