I got it from a local estate sale . I’m assuming it is 

Here’s a small grouping I found from the 533rd.    

I believe the 32460 number is the CAGE code for the contractor. 32460 is MIL-STD Corp. of Glenn Cove NY. I have never seen that sheath before; it might be something unrelated that got matched up with the knife, it has sort of a tool pouch look to it. The knife itself looks fine, a standard post-Vietnam Mk. 2 knife made by Camillus. I will be interested to see if it is identified by the experts here, I could not find anything like it on the internet.

For a good number of years, I did pre-purchase authentications and valuations on USGI 1911s / A1s.   In that time, I saw just about every permutation of bubba-fied mess, bullseye conversion, and other maligning of original examples.   While that still makes this just one guy's opinion, I wouldn't put another dime into this pistol.    She is what she is, and her nickel finish is part of her history.  It's also a throw-back to an arguably better time when militaria was largely still historical artifacts - and not a "what's it worth" Olympic event.    An exception would be if it's a "labor of love", and one would pay to de-plate and refinish it for their own appreciation.  But in terms of enhancing value, you're likely to spend more than the pistol ends up being worth - in dollars - to do so.   My recommendation would be to have a qualified gunsmith ensure that it is safe to shoot.  If it is, I'd plop an upgraded spring set in it, add a shock buffer, and enjoy shooting light loads through it every so often.  This is an old war horse that may appreciate stretching its legs again.  

I owned one. It is a miserable bayonet, neither fish nor fowl. The offset handle is awkward to use as a field knife, much less as a fighting knife. No natural balance at all and almost impossible to use as a tool. Then as a bayonet it is just unwieldy and a bit heavy for what it is. They would have been far better served to just produce a simple spike bayonet for the rifle (like the No. 4 Mk.1 Enfield bayonet) and an actual field knife. IMO, it is one of the worst bayonets fielded in the modern era, and that is being charitable.    Royal Enfield submitted the design in the US XM9 competition. Thankfully it was quickly eliminated.

Sheri,   dhc gives some solid advice with his previous post.  I did a quick search and the 110th was at Omaha on D-Day.  The 29th Division references Batteries A, B & C and some of their engagements but nothing specifically on Battery E.  That doesn't mean that they weren't there on D-Day but there also a chance that they could have come ashore on D+1.   I think I did find a picture of your guidon.  Also, you might want to start your own, new thread to get better visibility.   OD  

I’ve continued this thread on my Groupings thread in the forum section by the same name.    I added some close ups of the Amphibious Engineers booklets

Some pictures from the manuals.
