Milpar M7 Bayonet for M16 Vietnam War to 1980s Plus Find the Hidden Cat

Still yet another in my search for the perfect M7 bayonet. This one was closer but it has a few flaws. The black finish is mostly missing, there was a bit of improper sharpening near the tang and a slight bend in the bayonet ring. It does have the proper markings, Milpar and US M7. This one at least fits on a rifle but just barely.
In photo four my other 2 are there. On top is one made by Colt which is not military issue but is otherwise perfect. The latest in the middle and on the bottom one that is too rusted up . Eventually I will get the perfect M7 bayonet.
