From the pictures of the first one, I'm pretty confident it's a wide AM. The CAM A and M are practically touching, and in all of the pictures that you can make out, yours have a pretty pronounced gap. The position of the FG is another clear indicator, but I can't make out enough on the pictures... check this site out: http://lincolncentresource.com/wideams.html Very helpful with pictures and descriptions.
Ok. Ive done my reseach. I got four good chances on the 1992's, but the 1990'$ , im banking on those.
Well I think you need to do more research because so far, all the photos you've posted on this thread are WAMS, not CAMS. I know it gets exciting when you're on the hunt for the holy grail, but even Indiana Jones remained open minded to the fact that he didn't find what he was looking for, at first.
