Yeah most likely.

Super quick question too, Is there anyway good to fix the pitting? I was going to use bondo after recommendations, But does anyone advise against it? Is there a better way I should use? Or is Bondo all good?

Update:  So far I've gotten all of the surface rust off the topside of the helmet I'm slightly struggling but getting by on the inside rust too. There is also a lot of pitting from the rust, But otherwise I am good to go.

I think the idea came from one of the first posts, I think the guy said KA-BAR on accident instead if M3.

Could be yes, I'm gonna do some research, see if it will in fact fit into other scabbards, (Original or reproduction)  I'll let you know as I go on.

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.
