Sorry for any confusion. What I am looking for is preferably a non metal replica of the m3 trench knife to put into my original scabbard. As far as I am aware, a KA-BAR knife cannot fit into the m8 scabbard. And I was preferring a plastic or a rubber knife to go along with regulations at reenactments. It's not that I can't get a real knife, I'd just like to get some "use" from it inside of a battle reenactment or a demonstration, or whatever the cause may be. If this all sums it up.

Thank you Jake. I’ll send you an email

Thank you for your assistance. 

The belt the field grade officers wear in the Old Guard has reverted to the 1.5”all gold braid, which was true Army wide until 1937. Shown below on right in 2025.   The female officer in Imxs’ picture above is LTC Meghan V. Ederle. Her belt braid is all gold like the officer above on right, not in branch color.  Company grade officers of the Old Guard wear the traditional belts with four gold stripes interspersed with the first named color of the branch, which is infantry blue.   According to Ranger-1972 above, the four stripe pattern was worn by company and field grade officers of all branches, in all the colors, from 1937-1953.   Evidently no one makes the braid with four gold stripes in any color but infantry blue anymore, so company grade officers of other branches use a belt with cap band type braid in the branch color instead of the pre 1953 four stripe braid.   I can’t find any regulation for this new belt with cap braid but Marlow White sells it, albeit with a different buckle. In my opinion it’s a shame they don’t make the traditional four stripe braid in all the colors.    I saw the cap braid belt being used with the traditional 1851 pattern belt buckle during the recent presidential funeral service in January 2025.   If anyone has any further information on current regulations for this please share.   

Thank you! This is definitely a great thread with a ton of useful info/pictures. 

I was thinking the same. I. Think he was 6th Illinois Cavalry 

Interesting photo. I never would have guessed that was a military uniform.  mikie

Kfields-   Well bought!   UFH changed to the round fuller sometime in 1942. Approximately 1/2 have square fullers ( early). Then later, round, as is yours.   Nice display.   hyrax222

I went to their website and all seems good, I have never done business with them, but I have done business with over eight vendors in the UK, via the internet, and it was all good.  Caveat emptor, they advertise "THEIR" plastic M3 will fit into "THEIR"  m6 sheath. Prices seem very fair. The shipping could be expensive tho.
