The hands all look correct for the watch but that isn't to say that any (or all) of them have not been replaced at some time in its life.
Those three hands all started life with paint over the whole hand but when they are pressed on after a service or maybe even during manufacture, the paint often flakes off of the pipe. This leaves it with the effect you are seeing. As none of the hands, including the chronograph second hand, have the bare metal of the pipe showing, I would hazard a guess that they have all been replaced at some point in the last 40 odd years.
