I asked (in response to John Greedy's date of the MILW logo change):

Was this also the date of the change of reporting marks to MILW?

Richard Hendrickson replied:

Obviously not, since photos show the MILW reporting marks in use as
early as 1936.

Glad to confirm this, as I did think it must have been
earlier. Does someone have that date?
