Tom,
As I said in my note, the gray smokeboxes may have been used earlier,
and, I find in fact, they were. In looking at Perry photos from the
Denver Public Library collection and in Corbin's book, I find some, but
not all locomotives with gray smokeboxes much earlier. The oldest one
that I can find appears in Corbin's book on page 34 of A-6 4-4-0 #550,
taken at Council Bluffs, IA on Sept 6, 1897. It clearly has a gray
smokebox in those two photos. There are several photos of locomotives
in 1900 with gray smokeboxes. I assume that graphite was used at that
time. They probably had problems with regular paint, available in those
days, burning off the hot surfaces of the unlagged portions of the
boiler assembly. The fireboxes aren't that clear as to color and the
cab roof color is impossible to determine in the b&w photos. There are
photos taken after 1900 which show locomotives that appear to have
black smokeboxes, particularly as delivered from the builders.
