A bit short of 3 1/2" tall, gold embroidery on mesh backed black felt, I think for dress uniform. NOS or New, Old Surplus item, I don't think it was ever on a uniform. Ideal for any WWII collection.

The original Administrative patch featured a "V" on an anchor but was changed to a Caduceus in 1935. They don't necessarily indicate medical, they have a broader meaning.
