That paint on the old broken spring used to be a straight line; so
why does the old spring still show 7 spirals as if it's still wound?
Also notice the winding spirals are in the opposite direction from
the original.
Why would that be?
Because when the spring is compressed, it's not exposed to the elements.
When you wind the spring it shortens in length by a few inches, then you
tighten it. When unwound, that extra length is visible.
