Liz (Fowler) & John Beecher Perry Family

1902~ John Beecher Perry, New Haven Grays (CT National Guard)

Army uniforms changed in 1902:
Olive drab wool and khaki cotton service uniforms introduced; blue retained only for dress, full dress, mess dress, and special evening dress, trimmed with branch of service color. New patterns of blue full dress and dress uniforms adopted for both officers and enlisted men. Leather color changed from black to russet. The M1902 visored cap is adopted.

New Haven Grays discharge papers show mostly Jan-Jan service dates for JBP:
1897-1900, 1900-1902, 1902 (thru June), 1907-1909, 1909 (thru Apr)
The Grays went to the Mexican border (Pancho Villa), but probably not JBP.
