No idea about the hallmark but I kept  photos of another pair of these sweetheart glider trooper ear rings which look US made but I have listed as being made in Asia.   Maybe they started off as US made miniature glider trooper wings which were later made/modified by a jeweler into ear rings in the orient.  I don't see any hallmarks on the ear rings in these photos.        

I've got a US army 1980s NBC jacket and pants. I only bought it for collection purposes therefore I don't mind the fact that it will loose it's chemical protective factor, which I was already told that it's expired when I was buying it. The seller claims that they have washed it before but there's still some charcoal left in the pants and at the tip of the arms of the jacket which I want to clean easily. Is there a way I could clean the suit without damaging the fabric? I mean it's already used to so it is pretty damaged actually but I just don't want the outer layer to fade and/or get any charcoal stains. Should I wash it? If so how? (Could it damage the washing machine somehow?)   I have already seen in another forum that people have been talking about ripping the charcoal part off. Y'all think that's doable or just an even worse idea?  

I purchased this mess kit years ago and loved the detail on it.  I reckon between meals a cook who is a skilled artisan has some time for some etching.  That, and I collect 40th Infantry Division items from WWI through the Korean War.                                         Other documents like Naturalization Record, Full WWI U.S. Army Transport Records, and misc. documents.     40th Division_4Theodore Kutrukis.pdf

NICE!!  It's good to see one on a jacket.  

Scrolling through old armor posts and didn't see any of these.  Just wondering if anyone else collects them?    

Here's a selection of the Branch Colored NAME Tapes of the 50s, while some of the type were made in the states, most were made overseas, alot in Germany, some have way different methods in making of them, like BeVo could be seen, Fully Embroidered etc, but with the standard method, note how alot of them have very neat even uniform lettering.   https://www.usmilitariaforum.com/forums/index.php?/topic/4837-color-name-tapes/#comment-2890736     https://www.usmilitariaforum.com/forums/index.php?/topic/28547-nice-colored-name-tape-set-on-hbt-and-fj/  

Should bring this one back to the top.  Lots of good stuff out there.

Until someone has a different identification for the oval, I'll go with the 326th Airborne Engineer Battalion.  Thanks.

Another.
