I haven’t seen a helmet used with multiple covers. I don’t see why you couldn’t use it like this though. Just the matter of why? What does the helmet look like with the desert cover removed?  

Is this a modern strike? 

Looks legit, I’ve seen earlier PASGT helmet covers without any foliage slits. The NSN number is in the database as well. 

Quite a haul at the flea market today, 4 miles of walking around  baking hot even at silly o clock this morning. Checking it all in and noticed I had picked this up amongst a pile of wartime ephemera. U.S.Army General Depot G-65 Portsmouth 1942-45.  I also picked up a number of civilian wartime food tins , many complete plus various dried egg and milk tins from US and Australia although not sure if they are wartime or postwar. More research needs doing on those.

Attached is a photo of the M3 Camillus blade. The blade is almost sharp enough to shave with. I believe you are correct  in assuming the blade has the original factory finish. Not sure what "line of white " means.  VNAMVET70

Very nice grouping! Do you have the DCU helmet cover to match the DCU shirt?

I agree this dose not look like a typical Korean made patch but I don't know why any one would reproduce it. It is not an actual unit patch but more like a moral patch but also not quite.  The U/7 was a program the 7th Div used in Korea, it stands for "You are the 7th Div and the 7th Div is you". They would have been procured by the division or maybe the 7th Avi and maybe they went out side of Korea for them. They were made for most the units in the division, they were not something people would eagerly purchase and wear. I was in the 7th Div in the late 1960s when these were every where and don't remember ever seeing one actually worn and you did't even have to buy them. I don't know if the program was continued after the 7th Div left Korea. 

Thank you both for the information. Seems most plausible the award was made during WW2 or inter-War given Norway's neutrality during WW1.

Also for the full size medal ribbon drapes, the Marine Corps wears attachment devices centred on the ribbon in a vertical row. An example from another thread:    

Every word has a specific meaning but a lot of people don't seem care, to quoit the caterpillar in Alice in Wonderland "the question is who is the master you or the words". The different names for fabrics are all for different fabrics here is the answer to your question from the internet;   Though poplin is sometimes conflated with twill, poplin and twill are not woven in the same way. While twill is also a plain-weave fabric, poplin is woven with a fine warp yarn and a thicker weft yarn. While both are strong materials, poplin is often softer than twill. Poplin is also more breathable.   A lot of people don't know what something is and don't bother to look it up and just use a term they heard some where, if the material really matters to you it is best to ask for a close up picture if it. Remember google is your friend and will answer your questions but you may have to check a couple of sources to make sure they are the same.
