This is an U. S. Army issue, U S Army 50th Support Group, enameled metal Crest (Distinguished Unit Insignia), in brand new (never issued) direct from government contractor condition.   This crest was manufactured on a government contract by SUSCO (Sugerman) (SUSCO was purchased by Ira Green Inc.) and is hallmarked "S 21  Made In USA". What you see is what you get.

NOTE:  I will combine shipping cost.   

Nice insignia for any collection.  What you see is what you get.

Note:  My Company took over the retail sales of crest for Ira Green in 1997. 

Having sold my U. S. Military Insignia business (H. J. Saunders U. S. Military Insignia, Inc. - America's Largest Retail Insignia business) after 35 years, in November 2003, I am now selling my personal collection, many of which are government contractors samples, accumulated over the last 50 years.
