I dont who this ebay seller is and I am not covering for them so you can shove that statement were the sun doesn't shine.   I just cant stand people like you who constantly complain and cry over everything and you are one of them. 

This is just a guess but this looks like a patch worn by members of an on base (Eglin Air Force Base) scuba diving club for service members and their dependents.  Below is a picture of a similar patch for a different air force base.

Hey Justin,   Many thanks for the comment.   Drew

Hello doyler,   Many thanks for the comments and information.   Drew

Absolutely outstanding!  All the details really set this one apart from some dio's I have seen.  Very impressive work, Manu.

Ooh, I totally admit it and own up to it. You ... however have missed the point. Maybe you know this seller and are covering for them. Must be hard to live in your perfect world. Good day to you as well.  

As some of you know, I have been working on the history of the early USAR / ARNG Special Forces units, which includes the 300th SFOD (FD)    I have recently been talking to the son of one of the original staff officers who stood-up the 300th SFOD in Mar 1955. He has his father's original insignia-I am waiting on some pics of his unit crest.   I plan on publishing an article on the 300th SFOD in "The Drop" within the next 6 months.   I promise you it will be much more than a couple repeeated lines from the internet. It is all based on original / period document and publications.

Honesty does go a long ways and so dose doing your due diligence. You messed up buying from this seller and now you are upset. You messed up by not acting fast enough. You could have gotten your money back. This all could have been resolved within 30 days. But you chose to drag it out and now you are crying about it.    The fact you say your feelings don't matter to you and everything means to me you know you screwed up and cant admit it to yourself.    Have a nice day.

It has a much smoother finish   I realized I should have taken a picture next to the version with the heavier "Pebble" finish-after I posted it    Here you go.
