Colt marked M7 quite curious

[Mister Moon]

Hi Marv,
Yes, i see now that i have one of your model put on the yellow paper.
About the "rare" cut blade, yes, it's true, it's the same cut that on my FZR.
Unfortunately, i'have any information for these M7 bayo.

Hi
It's been a while since I posted. Since then I found another of these 90 degree back cut Colt M7 bayonets and I was able to buy it. It is virtually identical to the one I originally posted.
There are six differences in this Colt marked M7 and the Imperial/Colt M7.
1. It has a 90 degree back cut.
2. It has grips with the threaded bushing imbedded in grip instead of a loose nut.
3. It has a round hole in the tang instead of square one through which the "U" shaped retainer passes.
4. It has a star burst peen.
5. The ears on the release levers on the pommel are shaped differently and do not have the punch dot.
6. It does not have the two holes in the cross guard by the blade.

Mr. Moon,
Here are some photos. They show the various differences that I have described above. Also, the grips on the 90 degree M7 do not have the hex screw holes as does the Imperial/Colt M7. Thanks

Just for the sake of better documentation. I have noticed a 7th significant difference in the two bayonets described above. The font on the cross guard is quite different, especially the "M" in M7. The picture shows how much different the whole font is. The top bayonet has the curved run out, the bottom one has the 90 degree back cut. Thanks.

Another forum member noticed something I had not noticed. Here's difference number 8. The Colt roll mark has a different font and the two lines are placed a little higher on the 90 degree Colt.
