Rare Original 1950s Navy HTU-1 Patch Helicopter Training Unit One Korean War Era For Sale

I got this with a collection of old military patches and photos that belonged to a Navy soldier who served from the mid 1940's up through the 1950's.  This is an original extremely rare piece. See all photos for condition and measurements.  I will be listening other patches and photos from the same soldier.  I can't find another original like this one so we are putting it up for best offer.
