by now you can see a slit between the pieces.
Hm... unfortunately i don`t have an empty SLR at hand to check - but what is the synchronization of the shutter and the mirror when advancing and cocking the shutter?
Will the shutter be cocked first and the mirror hinge down last? If shutter and mirror move simultaneously the effect of additional exposure on the neg should be stronger on one side and decrease to the other.
Also there must be some up-and-down movement. If there are pinholes in the curtain, the curtain or the film had to move up and down a bit when advancing/cocking to create these waves.
But how does variation in shutter slit width leave relatively sharply defined striations as shown here:It looks like the cloth focal plane shutter had a wrinkle in it, or was a bit twisted, giving you the wavy exposures.

Especially at larger apertures as also evidently used. The shutter is quite some distance from the film. Hence, the variations in exposure you'd expect from a shutter anomaly will be rather fuzzy and more like the vertical lighter bands in these frames. I could explain those from a wrinkled shutter curtain, but I find the dark lines puzzling.
It looks like the cloth focal plane shutter had a wrinkle in it, or was a bit twisted, giving you the wavy exposures. You mentioned "Advancing the film felt excessively though, and by the end of the roll, the shutter and the shutter button jammed" so I would think that the shutter is completely hosed at this point.
