Lumes on vintage 6917/69178s?

[Softswerve]

I’m looking at a few different 6917 / 69178 watches and am seeing both lumed and unlumed examples. The majority I’ve seen come with unlumed hands. If one of these come with lumed hands, does that mean it’s not an original part? I have a few examples below. Thanks in advance for any insight.

The topic has been gone over many times. Most of the time on a stone dial the lume will be in the hands but not always is the case. Without knowing history, who knows when hands were swapped out. Also, dials were printed not knowing what the lume setup would be for a particular watch and a T marked dial may have been installed on a non lume watch.
