Singing B,
Found some more information and pictures that may be helpful.
All: Can I assume Carl Eickhorn Waffenfabrik , Carl Eickhorn in West
Germany, and A. Eickhorn-Solingen (AES) in West Germany to be one in the same?
If so it appears he had a hand in the
Denmark m/62. The Haiti M5A1, And the US Colt "New Model" M7. Maybe others, I only looked over the page 2 results in the Link below.
Here is your picture of the cross piece with the US M6 marking:

Compare the markings on the Haiti M6, Note how deep the V inside the M travels down:

Also the Haiti M6 is shown with a U.S. M8A1 over Made in W-Germany Scabbard like your's.

The Haiti M6 doesn't show if it has phillips head screws, but I'd expect them since the Haiti M5A1 is known to have them.
To my limited experience with bayonets and scabbards the profile of your grips and the checker pattern look very much like the Haiti M6.
I found these measurements on the Link. Compare a US M6 to a Haiti M6 bayonet:
Blade length- US____ 6.75" HAITI___ 6.50"
Overall Length- US___ 11.375" HAITI___ 11.25"
Muzzle Ring Diameter- US___ .725" HAITI___ .725"
Information gathered from Ralph E. Cobb's
worldbayonets.com-The Collector's Edge: Bayonet Reference
Here's the Link it will open up on page 2, where I pulled the above from. There may be more that can be useful.
Link:
U.S. and U.S. M7 Bayonets
I quickly skimmed some other pages. Enough to see that Carl Eickhorn was involved in many Bayonets designed for other countries.
I also seen more Scabbards marked like yours and with markings on Snap Rings.
@Singer B,
Are there any markings on your Scabbard Snaps ?
Good Weekend All
