My feeling is IUW 11-3 is an early 70's to post war unit.

They have been shortened.

Ahhh, now I know where another member found the 99####, and I was thinking - where the hell it is stamped after NXSX - there is nothing to read.  It should be there, as 29NAVY said      phil.co1 - Why are you asked about price? Do you want to sell them or something? They are worth about what someone would like to pay for them...  Sometimes people think about his stuff and prices too much. We can always see a low version of USN black shoes for an astronomical price, which have been for sale for years!  List it on eBay for 0.99 starting price and then check the current value.

Upon arriving in France, the 40th Division was designated as the 6th Depot Division, providing trained replacements to other front-line units.  While the 40th Division did not see action as a complete unit, its members, including those in the 79th Brigade, were sent to units like the 77th and 79th Divisions for combat operations.                                                                                  

Best I could determine is that the actual designation for this patch is Inshore Undersea Warfare Division 11-3.  There is nothing specific about them with this designation in their active duty history that I could find.  My guess is that they operated out of Cam Ranh Bay as there is mention of a Vietnam War era active duty unit called MIUWS (Mobile Inshore Undersea Surveillance) 11, Harbor Defense Cam Ranh Bay, RVN.   I think the first change right as the war was ending  in 1975 was NRIUW (Naval Reserve Inshore Undersea Warfare).  There was a NRIUW 11-3 out of San Diego but no connection to this patch.  Shortly thereafter was another designation change to MIUWS (Mobile Inshore Undersea Units) which is a post war naval reserve designation and not the active duty naval designation of MIUWS.   This is where it confuses collectors as you have the same exact acronym with different meanings.  

I purchased this off FB 🤮 and at first glance I thought, well I'll take a chance, as it came with a vintage framed PH accolade (no cert) now that I have it in hand I'm skeptical, I think the engraving may be made to deceive as it looks sloppy, at least I have never seen this "hand" before in any authentic WWII hand engraved PH. Can I get any opinions on this please? 

Wow, some great stuff you got there!

love to see 3rd MarDiv. stuff, nice pickup!

Thank you Allan!   I heard that Type 10s were also produced/used between 1957 and 1967. From what I've learned online, most patch guides say that if the patch is a no-glow, then it should be WW2. I have to be honest, I'm a little skeptical of calling a patch WW2 era solely based on this criterion, but in this case, wouldn't this point towards a 1940s production rather than the later 1950-1960s era production?

During WWI, the 340th Field Artillery Regiment belonged to the 89th Division.  It was part of the 164th Field Artillery Brigade, a key component of the 89th Division.  The 89th Division served in the American Expeditionary Forces, participating in the Saint-Mihiel and Meuse-Argonne offenses.                                                                                             William Ferrell_35.pdf William Ferrell_36.pdf William Ferrell_37.pdf William Ferrell_38.pdf
