For those more interested in the shovelnoses than the Keokuk Union Depot, I did
some digging through the list archives and found comments (some from Marshall
Thayer) indicating that 9906-9907 got the Mars light in March 1940, 9904-9905
soon after that same year, and that 9900, 9902, 9903 and 9908 didn't recevie
them until after the war. This fits with what Nelson has been able to
document. Notably 9901 did not receive one, as it was destroyed.

Nelson, thank you again for taking the time to look and for the summary work.
If we're looking at late 1940s for addition of the Mars light to 9903 then
the modification of the KUD roof has to be later than that and Ken Martin's
date of 1955 for the roof change could well be right.
Knocking off the question marks one at a time,

Notes:
Mars light added to 9900 in the 1940s.
Mark Twain Zephyr (9903) received a Mars light in the mid-1940 (Doughty Vol.
1, p. 54)
Mark Twain Zephyr (9903) received a Mars light in the late-1940s (Lotz,
BB#23, p. 98)
"The first two units to get the enlarge headlight with an integrated
oscillating Mars light were Nos. 9906 and 9907 in March of 1940" (Doughty
Vol. 1, p. 79)
Several undated photographs of 9903 are printed in BB#23 showing both single
and twin headlights.
Summary
The non-articulated shovelnoses got Mars lights before the articulated
shovelnoses (as early as 1940).
Based upon photographic evidence, Mars lights were installed as follows:
9900 Between 1944 and 1954
9902 Between 1942 and 1948
9903 Between 1940 and 1951
9904 Between 1938 and 1940
9905 Before 1943
9906 1940
9908 After 1940
For the Mark Twain Zephyr (9903), Doughty says mid-1940s and Lotz says
late-1940s. The most likely modification date based upon data for 9900,
9902, and 9903 above is between 1944 and 1948.
Knowing the dates for the undated single headlight Mark Train Zephyr photos
in BB#23 could help narrow the modification date.
