Emerging shutter fault in Pentax Mx?

[PerA]

Hi!
I just noticed a problem with one of my Pentax Mx cameras (first rolls after CLA but not used since), see attached picture:
In many exposures (but not all) the last mm to the right in the picture is underexposed. I don't know much about shutters but
I guess this has to do with the curtains not being synchronized (or something similar). Anyone knows?

Usually, an underexposed edge is the result of shutter capping.

+1 It's usually a simple adjustment, but you have to know what you are doing and have the proper test equipment/tools.

Thanks both of you!

Thought I should mention that I later had the shutter problem fixed at Analoga kameror Stockholm, Sweden.
