CIRCA 1920’s–1942, US ARMY, 1st ARMY, SSI, ENGINEERS, ON WOOL, PATCH, VINTAGE
This patch does not react to ultraviolet light glow.
The practice of color inserts in 1st Army patches
dates back to WWI. There are almost an infinite amount of variations in
the WWI versions. Standardized branch color panels in the top of the
"A" came into official use in the late 1920's and lasted until 1942.
Collectors can find both wool and standard embroidered versions of these
patches. WWI versions will have inserts in the upper panel also in the
lower panel and combinations of both. The WWI inserts are usually found
in the lower panel between the legs.
