Below is shown the first olive drab cotton service breeches
photographed with a pair of 1906 spec. #846 cotton service
breeches for comparison. Construction appears identical
with the exception that one is khaki and the other olive drab.

I had previously believed that these breeches were issued
to accompany the first olive drab cotton service coats; however,
upon inspecting a list of early quartermaster specifications
provided by fellow forum member Jon Prost, I discovered that
it wasn't until the publication of the 1910 cotton service
coat spec. #1059 that an olive drab spec. #1058 was issued for
the cotton breeches; therefore, these service breeches should
be displayed with 1910 or later pattern cotton service coats.
On March 13th 1909, specification #1014 was published by the
USQMD for the production of a 6.5 ounce cotton cloth dyed olive
drab; this replaced a prior specification #991 (Aug 15th, 1908)
for cotton cloth dyed khaki.
On July 12th 1909, the USQMD published a specification #1038
for the adoption of the olive drab cotton service coat for tropical
climates. This was the first article of cotton tropical clothing
to utilize the olive drab cotton cloth. Prior to this spec., all
articles of the cotton tropical uniform had been khaki.
