IS A NEAT OLD LARGE (38MM TALL) INSIGNIA FOR THE 239th AVIATION COMPANY (ASSAULT HELICOPTER) TOROS ALSO SAYS FIRST IN KOREA. I'M NOT SURE IF THIS INSIGNIA WAS MADE DURING THE VIETNAM WAR OR EARLIER. I THINK IT IS JAPANESE MADE AND IT HAS NO MAKERS MARKS.I have collected military insignia and patches for a good many years and have decided to downsize my collection to those things that I have a specific interest in (U.S. Air Force items of the Vietnam era from Utapao RTAF Thailand and items from the old Hawaiian Division especially the 19 th Infantry Regiment from the late 30's thru WWII). I will be listing lots of patches and insignia plus a lot of other items a few at a time for quite awhile. Any clothing items are sold as a collectible and CANNOT BE GUARANTEED TO FIT so if fit is a concern please email me the measurements you need taken and I will do the best I can to answer all your questions!!!!!!
