This is a new to me wing. Meyer incised shield and sterling mark. I believe this is what is considered a first pattern.

Justin, thanks so much for your effort in looking him up! I think we can completely confirm that is him. I found this document based on what you found that confirms naval construction, reserves, naval aircraft factory in Philadelphia. This lines up with what is written on his uniform tags. I’ll do some more digging on this. 

Did anyone ever contact the Gwiazda family? My husband was his neighbor in Phila. 

I think that pin is 100% right, perhaps the fastener is just a replacement.

That’s a really cool example,   Kurt

Nice group!

Here's a dog tag to a soldier at the 15th Port HQ Trans Corps. From Altoona PA

and...   Staff Sergeant Donald E. Rey U.S. Army Holt, Michigan   Donald E. Rey enlisted in the U.S. Army on October 20, 1942, at Fort Custer, Michigan. After completing basic training, he was shipped to northern Ireland for amphibious training. On D-Day he landed with the 8th Infantry Division on Normandy Beach. After moving inland, he was captured by the Germans on July 4, 1944, near the Cherbourg Peninsula. He remained a P.O.W. until liberated 10 months later. Don reenlisted in the Army on April 4, 1946, and returned to Germany to serve with the 72nd Constabulary Squadron in Boblingen. The United States Constabulary was formed in 1946 as a law enforcement agency to curb anticipated chaos, criminal activities, and localized insurrections in the U.S. Zone of Germany. The Army created and deployed “The Constabulary” as a organization that combined the attributes of the Horse Cavalry with the striking power and mobility of the early 1940 Mechanized Cavalry. Besides the mission of protecting the infant civil government, they had roving police patrols. They also policed the checkpoints along the borders with the Soviet Union. Major areas of concern were the rounding up of Nazi fugitives and control of the many DPs (Displaced Persons) scattered throughout the country. All criminal, black market, and common crimes were dealt with.   Troopers in the Constabulary used jeeps, armored cars (M-8), light tanks, and horses in this mission. The weapons used were the .45 caliber pistol or machine gun, M-1 rifle, carbine, or Thompson submachine gun. The Constabulary was established as a Mechanized Cavalry unit with a troop consisting of 140 men, four troops to a squadron, plus headquarters. With three squadrons to a brigade and three brigades, it had the potential for 36,000 men, but most feel it never reached that. By late 1947 and early 1948 it became apparent that the worst fears of the Americans did not come true, and that Germany, with its new local government, had taken over most of the responsibility, so the Constabulary was slowly phased out. Most units became combat units, but some were deactivated. In late 1952 the Constabulary gave up their colorful uniforms and equipment for good.
