Quite interesting! This is pre WWI for naval guns.
I've recently seen some casting video using the exact same setup as used around 1:40. This technique must be robust and efficient. Still can't totally wrap my mind around the sand mold tho. The "making one mold for one piece thing" seems like a lot of work for one object. I probably miss something.

the technique they use is the same one we've been using for the last 6 thousand years. using sand for the molding goes back 3 thousand years. before that it was carved stones for molds. using sand gives you a more precise mold of the object(s) to be cast because you can have more than one object in the mold, you just have to make channels for the metal to travel
