You're probably correct. Most of what I've picked up are most likely Greek returns. Almost every bayonet they used has a serial number stamped on the guard. These US scabbards aren't what I bought with the bayonets, but a high percentage of what's around the last few years was lent to Greece. Usually pretty cheap though. Picking up usable non repro US scabbards under $20, or when Dupage had Greek ENS and unmarked W German M1 bayonets $20-$30 were great deals. Especially if you had a US M1905 missing internals or grips! 

Thanks so much for sharing this detailed information as well as some great photos! (I do find the modified vests most interesting! That MA2 modification is great!) You have obviously been more successful in your research than I. In the info provided concerning the 1966 Independence vest contents you mention "a plastic box with medicines", would this be a PSK-2 or SEEK 1? Those kits also contain the malaria and water purification tablets. You also mention an Aviators First Aid kit with morphine. I believe the WW2 and mid /late 1950s kit had that item but was removed from the kit issued in mid/late '60s. I suppose were only talking about a few years difference and many these items remained in inventory.  I imagine the Flare gun mentioned would be a Mk-79 launcher. (Red flares a no-no as well as an uncovered SDU-5/E. It certainly made sense to transfer the radio out of the seat kit and keep it at close reach being probably the most important component of survival kits.  By the way, the Marine vest I show was used in 1966.   Thanks again, Scott

For Further Consideration:   I didn't fly.  Consequently, I knew my time on active duty, and in the USAF, was limited, so I made the most of it.  I was on active duty 1992 - 1996, during those terrible "McPeak Years", frought with "banked pilots", base re-alignments and closures, and reductions-in-force.   Nonetheless, once I got my honorable discharge, I was able to enroll in VA medical care, which spared me health insurance premiums, I had no student loans to repay, and I retired from state civil service after working twenty years, with 24 years credit for service because of my active duty military service.   More importantly, what I wear on my blazer lapel I wear with pride. Not because of patriotism, but because I earned it.  Nothing beats the feeling of having accomplished something, and being recognized for it.  I could have done my job in any branch, but I learned and honed skills that stood me in good stead for the rest of my life.   As I mentioned in post #48, it's highly unlikely I would have reaped any benefits had I not been in the military.

Your USN modified with Velcro badge placeholders are great examples.  Tough ones to find and congrats on a nice score!  

These look like they were used by Greece. The metal tipped scabbard were common to Greek used Garand bayonets and retamping was a common practice I recall for the Greek used ones.
