After looking at a few hundred image tiles per day, I finally made it through all 8400+ photos.
By this, I mean that I looked at all the tiles, and only opened for full viewing those tiles that
appeared to contain something of interest.
The vast majority of the photos were taken indoors and similarly posed. Those troops belonging
to Co. I of the 104th Infantry were photographed outdoors wearing wool shirts (without coats),
a mix of wool or cotton trousers, campaign hats, and either a M1907, or M1910 cartridge belt.
The seated posed photos showed soldiers in full uniform, either summer cotton, or wool. These
soldiers wore either a campaign hat, or the olive drab service cap first issued in 1911 after the
army dropped the bell crown style. My impression is that there was roughly a 50-50 split between
these two styles of hats used. It dawned upon me, after looking at the first few hundreds of images,
that even the soldiers wearing summer cotton uniforms were all wearing wool service caps; then
I remembered that the cotton khaki service cap (bell crown style) was issued starting in 1906 and
discontinued by around 1910. Those caps made of cotton after 1911 are personal purchase items.
I don't recall seeing any service cap other than woolen ones appearing in these photos. Not one of
those pictures showed the enlisted cap disk.
Occasionally I shall update this post with a few images that I downloaded because they contained
something unique or of interest.
I'll start with this image today: Mr. H. Kiedenaar, 101st Infantry, Co. C.
I think he lied about his age.
