187th Korea ? With arrowhead ?

Could this be legit ? Could it be I’ded ?  Found in a bottom of a bin of old toys and baseball cards at a yard sale. 

I'm still puzzled by the origin of this (presumably) U.C. bayonet I picked up somewhere (gun show?) some time ago.  The serial number on the ricasso has me stumped.  I've read that normally the presence of a serial number on a U.C. bayonet suggests it is a foreign (Italian, Norwegian, Danish, Argentinian, etc.) return of a post-war used bayonet.  I haven't been able to locate any other distinguishing marks that would indicate it had been overseas.  The serial number is seven digits, not the five or six I've heard is the norm, and the numbers are stamped uniformly and fairly straight.  The "1" in the serial number is of interest, because it lacks the little flag at the top.  Any thoughts?  I've asked elsewhere about serial number ranges for post-war bayonets but have been informed that no substantial data base exists for them.

AH, THANKS.  THAT EXPLAINS IT— NEVER WORE THE ACU OR WORKED WITH PEOPLE WHO DID.    

Yes a rare Korean War patch.   15th TRS and Project Honey Bucket:   Project Name: Known as "Rosco 15 Honey Buckets".   Aircraft: The unit utilized Japan-modified RF-86 Sabres, with only 6 produced.   Operational Locations: Bases included Komaki, Japan, along with Taegu AB (K-2) and Kimpo AB (K-14) in South Korea.   Role: The 15th TRS provided specialized tactical photo reconnaissance during the Korean War. 

Agree with KurtA, it’s a cast copy of Robbin’s type pilot wing.  It doesn’t have the right pin attachment either   Keith

Using his name as CO, there does seem to be a connection with the Land Warfare Laboratory at Aberdeen Proving Grounds, it seems that they contracted some of the work out to Battelle Research out in Ohio. Also, the ACTIV unit was composed mostly of civilians according to COL Richard Clarkson (CO) final Report from 1974.

Yep....I saw that one on ebay and who won it. Nice!!
