halo 2 odst?

So I was looking around for some easy to build halo helmets and came across this gold ol Halo 2 odst helmet seeming easy without thinking i constructed it and started with all the hardening. once it came detail time i couldn't find any reference pics? Im sure if you were ever on halo costuming you saw this also. I've built it up to far to stop now so whether its real or not ill just add my own details. So please if you have any info on this it would be much appreciated

There are quite a few odst shorts and commercial on youtube such as "we are odst." Also if I recall correctly Halo: Forward Unto Dawn movie has a few odst helmets through out it. I think Agent Florida has a blue Odst helmet in Red Vs. Blue Season 10

THe best thing you can do is a google image search for "Halo 2 ODST". I did that and found these:

If you want to find some more references for detail, you might just have to search and try to find some more pictures. It might take time, but if you want that detail, it will be worth it.
