Found another example on page 205 of Flightmaster Only a 145.026 with type B3 3-6-9 Without Dots dial.
I remembered an OF member
@ATWG had a new old stock 145.026 with a B1 Transitional dial. It still has the original factory film on the case!
It also has an hour hand similar to your 145.013
I've also noticed with these hour hands the black paint does not come up as far on the hand which tends to accentuate the shorter lume channel.
ATWG example.

and another 145.026 from OF. Also notice the difference in how far the black paint goes up the minute hand on this and the above example. It appears that differences in how the black paint was applied can be found in both the minute and hour hands on Flightmasters.
