Gun for the Northeast Passage (current news overlap!)

I was watching Sal Mercogliano (What's Going on With Shipping - highly recommended!) this morning and one of the news stories he discussed was a recent successful container ship transit through the Northeast Passage. Not the Northwest Passage of sea shanty fame, but the passage from Europe to Japan over the top of Russia. Well, I happened to just finish editing a video on a gun from one of the early expeditions to fine that passage! It doesn't post until September, but I have made it accessible to all Patrons at the $5 level and up for early access here:
