Pre WW1 Collar Insignia Officers? Enlisted ?

[TMCA05]

 

I have a 15" x 8" group photo of Company D, 1st Artillery Regiment. It has about 97 officers and enlisted-men in the photo. Almost all the them, both officer and enlisted are wearing the same collar brass.

I assume it is 1902 pattern insignia, but I am not really sure.

I thought this type insignia was only for officers?

This is a pre WW1 photo, Was this common in that period?

I am guessing the photo was taken between 1902 and 1914, but I am not sure. Any ideas?

 

Thanks Dave

Collar disks we me were introduced for enlisted men around 1910-12 I believe. Before that officers and em wore the same style.

That should be "were," not "we me were."

Thanks, I see now that the EM disk came out in 1910, so I know this photo pre-dates that :-)
