It’s marked MW A4 on the interior

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.  

Intended to go in the Navy but ended up with an Army ROTC scholarship.  My primary reason for joining ROTC in 1976 was that I wanted to go to flight school.    Now why I stayed in for 27 years?  Looking back on it I would say stupidity; I certainly would not do it again if I had a do over.

Here's a better picture plus a 1906 Springfield cut down by UFH. Both are beak/bowie points.
