I hoped it would be very easy. Just put the upper loop over the top and then the second loop. It turned out to be a little more difficult than that. My fingers seems to have grown bigger and less sensitive than I remember. It's still something that can be done during game.

By the way...
The signal on the picture is according to "the internet" 16 as in the 1799 (or is it 1797?) code book by Howe. I only found the flags for 16 and 39. Anyone know the rest?

I've found Pophams book with the full 1803 code on Google books online. According to what I've found it's the same flags but new numbers assigned to them?
