Not sure on the date of this bike. I would guess 70s which would make it french thread (clockwise loosen). However, it doesn’t move no matter which way i try to spin. Any tips?

What’s the width of the bb shell?
“Not moving” is a common status of many such bikes, which makes knowledge of right direction crucial… 🥳
From my experience this side would be clockwise to remove. If it’s stuck i would try to put a large adjustable wrench on it with a pipe for more leverage.
French thread is counter clockwise to remove on both sides
Most French bikes before ~1983 use French thread.
