Demonstration of the elevation system on the strv 103
I’m not perfectly sure but I don’t believe these are the full extents of the elevation system – the depression is probably close to the max but I think the elevation could go another couple of degrees. To add to your enjoyment, here are a few pictures from the manual that shows how the system works. “Kvävgas” means “nitrogen”, and “olja” means “oil”.
By the way, in case you ever wondered what the heck “elgon” means in Swedish and been unable to find out (the word isn’t in the Swedish Academy Dictionary and is basically ungoogleable), the appropriate English translation is synchro. Naturally, I mistranslated it at first, so where it says “resolver” in the schematic above, it should say “synchro”.
