Original World War II 7th Service Command patches are authentic, vintage military insignia (circa 1942–1946) that do not glow under UV light. These patches typically feature a white or cotton gauze backing, indicating they are not modern reproductions. They represent the logistical command responsible for states like Minnesota and Missouri.

Key Features and Identification:
No Glow/UV Test: Authentic WWII patches generally do not fluoresce under blacklight.
Backing: They often have a white, or light-colored, flexible backing rather than plastic.
Construction: Usually embroidered on felt or cotton twill.
Design: The 7th Service Command insignia generally features a specific emblem design (often with a numerical or symbolic element, depending on the specific variation, sometimes confused with the 7th Army, but officially the 7th Service Command for the Midwest region).
Condition: Often found in used or “unsewn” (unused) condition.

Description/Blazon
A white seven pointed star 2 1/4 inches (5.72cm) in diameter with one point up pierced by a similar figure 1 1/16 inches (2.70cm) in diameter with one point down, all on a dark blue disc background 2 1/2 inches (6.35cm) in diameter.

Symbolism
The design is arbitrarily selected to represent the 7th Corps Area Service Command. White, being a mixture of all colors, has been selected for the reason that Corps Area Service Commands may be composed of all arms and services. The geometric design represents the Command’s numeric designation.

Background
The 7th Service Command Headquarters was located in Omaha, Nebraska and the Command was responsible for the states of Colorado, Iowa, Kansas, Minnesota, Missouri, Nebraska, North and South Dakota and Wyoming. The shoulder sleeve insignia was originally approved on 18 Jul 1941. It was amended on 18 Sep 1941 to change the description. On 14 Oct 1941 the insignia was amended to change the background color from olive drab to dark blue.
