Dave......thats the complete list...........no Combat Observer, no Tech Observer, nor any of the Lettered or other Specialty wings. The Combat Observer shown is one of those that appeared in the early 80s(?)....it is in fact a very well known NS Meyer pattern badge. The Tech Obs is of the same vein, once more a known Meyer pattern badge marked to Josten..........not correct.
In my short time of collecting I never once saw a Josten wing badge marked in the center....always lower right corner and usually at an angle. And never deeply pressed........some reserve was used in marking these badges.
My opinions only...................
Thank you for stirring my collecting juices a bit. You've peaked my interest with several of your statements and I'm hoping you'll elaborate a bit with some examples. I searched through numerous books and a couple of websites but cannot find an example of Meyer's made Observers badge identical to the earlier depicted Josten made Observers badge. Here's a comparison shot of a WWII era NS Meyer-made Observers badge and the Josten example. Was there another Meyer's pattern used for Combat Observer?
