I don't know about other swords, but both of my WWI M 1852 swords have visibly curved blades that are not photographic illusions.  This sword was owned by Capt.  Irving Reynolds "Skipper" Chambers (1893-1979),  USNA 1915,  only son of Capt.  Washington Irving Chambers (1856-1934), USNA 1876,  the "Father of Naval Aviation", who as  an ensign was one of six officers attached to U.S.S. Thetis under Captain Winfield Scott Schley during the "Greely Relief Expedition"  to the Artic in 1884, and later the first officer in charge of naval aviation in 1910 before there were naval aviators.   The younger Chambers purchased this from the Annapolis naval tailor and outfitter,  F.J. Schmidt (1859-1939), where you see a lot of uniforms and swords of Annapolis men from the first quarter of the last century.       

"Field" Police. 

I have all the parts for the trigger group. But something is seriously wrong with the trigger pin. It is stuck solid. I’ve tried banging away with a hammer and punch (at first quite gently but harder as my frustration grew). It moved out maybe half a millimeter. And that’s it. Notice that one of the punches has bent, but the pin won’t budge. The housing came with the trigger installed, but without the plunger assembly. I can only guess that at some point someone took it apart and removed the plunger and put the trigger back on, maybe with a wrong pin? After my grind job, the trigger swings free. I am perplexed. 😕 The only thing else I can think of is to drill the darned pin out and replace it. 🤬 How is your day going?  mikie

Its just my opinion, but I would lean more towards "sweetheart" or patriotic jewelry, myself. But still really neat.

Wonderful honoring of Fireman 3/c Fankhauser. He was initially listed as MIA on September 3, 1942.

That is pretty cool.   Many famous military heroes would auction off things (like wings) for charity.  Jimmy Stewart auctioned off his wings for various charity events over the years.  I had a chance to bid on one of those lots many years ago.  There is a lot of stuff (apparently) out there from Paul Tibbits IIRC.   My wife's uncle was a Hollywood producer of some renown and worked with Audie Murphy when he was making movies.  Mr. Murphy used to give away his medals to fans if they asked (especially if the fan was an attractive girl and he had been drinking).  So he had a steady stream of "replacement medals" from the US Government. At one point, Audie (who was trying to get a role in a Dirty Harry movie) had offered his medals to him.   Also, a family friend knew Jimmy Doolittle very well (and Jimmy Stewart) when he was working with the USAF Academy. He told me that Gen Doolittle would offer them all sorts of memorabilia (including his wings and medals) if they wanted them. My friends knew I had started collecting WWII wings and were going to ask him if he had anything to let me have, but sadly, he got sick and died before they had a chance. I did get a Christmas card signed by Gen Doolittle that they had kept.      So cool you got the wings.   P  

Not only are they soldiers, they are combat police soldiers.

Thanks for posting about the 101st 1st Brigade’s activities in Vietnam, 3338thqmtruckco. One small footnote: other units also wore the full color version of their unit insignia’s until late in the Vietnam War. For example when I was in the First Infantry Division (1968-1969) in Vietnam we still wore the full color version ”Big Red One” patch.   Subdued patches were made mandatory on the field uniform in Vietnam starting July 1, 1970. But, if there’s one thing I’ve learned, both as a collector and as someone who has been there, what one unit did in Vietnam … even in the same Division … could be entirely different than what another unit did.

to a photographer Im sure they had no clue. if wearing a uniform its a soldier. 

The official caption says "German soldiers" but the emblem on their caps looks more like police ?
