Very kool....I found a receipt for cases of whiskey bought with US Army dollars for "medicinal purposes" from Edgewood Arsenal 1930s......good times!!

Here is what I would consider a WWII vintage AMCRAFT-made wing. You can see that the base wing is (like Marty mentioned) a "target" and not an observer badge.  You can also see the distinctive AMCRAFT type forcer that gives the badge a "pinched" look--also the hallmark.   Ive always liked the AMCRAFT patterns.        However, it seems that AHD (Dondero alpha/numeric code = D2) bought or acquired the dies and made similar wings (probably late 50s/60s). The pilot versions are rather common, but IIRC I have seen some of the other ratings with the D2 or Dondero hallmark.    Note that the back is not an exact match to the war time AMCRAFT-made badges.  I do not recall, but I believe AMCRAFT was not a company that survived into the post WWII reductions of the military and was likely out of business by the Korean war.  

I was gifted these today by a friend who is always going to estate sales. Military items are not his forte'.

The quarterly ASMIC military swap held at the OWL fire dept just off I-95 exit 160 in Northern Virginia is a plesant 70-ish table show.  My purchases focused on Female, Formal, and few outliers.  The vendor with the bullion was well stocked and reasonably priced, very pleased to acquire the black background female hat device. Most of the bullion was made in Japan, and have pins for clutches.  The WAC collar pins and hat device all original pieces with the enlisted sets all being different, see back sides.  A few Chaplain ID bits, Lt Cmdr shoulder boards, the NOS Rabi pins in package very nice, the small blue book is a religion dictionary about WWII era.  The sewing kit was reported to be WWII Navy but it looks more like 1960's, thread has some use, most of buttons present.  The shemaghs were both made in India, NOS with many quality control stickers on them in non-typical colours.   As usual it was a friendly, no stress show with a wide variety of militaria for sale.  If there is interest, maybe I can make photos of a selection of table offerings, next show is first Sunday in August.  Cheers, Armygas

Ita Vero! 

Pretty sure it's caveat emptor, not caveat venditor...

Correct

Looks like woodland to me?? Either that or I'm going crazy.    Wade

Here are some photos of my similar Bombardier wing for comparison.  

Depending on provenance, I think $1800 is a ballpark.
