If you don’t have a ruler then an A4 sheet of paper is 8.3″ wide so use that to check it diagonally, if it’s the Columbus it should be larger than the paper, there is also a 9.2″ version of the Amundsen system as well as the 8″.
Oh yes, there’s a second Kodiak on page 11, that’s odd!
Please excuse spelling/typos. Apart from being a clot it turns out I had one on my cerebellum that's now causing various problems!
