If they're brass, it would weight significantly more than aluminum ones. Try weighing them and see.

The way I understand it, the brass color is the actual anodizing. The USGI spec magazines have a grey coating that is applied over the anodizing that wears rather easy.
Clandestine is correct. The gold or brass color is anodizing. I have a few of the exact magazines that I took back from Vietnam. I would say they are collectible, especially if they have Colt markings.

they both weigh 2.9 ounces - so anodized it is
thank you..................
one is colt, the other is other is Simmonds M16/M16A1 CAL 5.56 mm
Both are from the same era
Good chance they might be Vietnam era mags.

I think they are - everything fits
and by the looks of them - they fired a lot of ammo
Was there any doubt?

Collectable? Worth $$? That would make my day considering I may have a few more than a few of those.
Could it be iridite?
The conversion coatings are intended for use on aluminum and aluminum alloy substrates that are not anodized. They are used to repair anodized coatings on aluminum. They are designated as a post treatment to ion-vapor deposition (IVD) aluminum used on many military platforms as a cadmium alternative or galvanic corrosion inhibitor. Type I and II conversion coatings provide corrosion protection on unpainted items, as well as improve adhesion of paint finish systems on aluminum and aluminum alloys. The conversion coatings covered by this specification exceed most commercially available products. This is a requirement due to their use on military aircraft.

The easiest way to find out is to look up the spec for the manufacture of the mags. I'm not the best person for doing computer searches but I'm sure one of our younger members can do it in seconds.

chromate conversion coatings are very common an aluminum items subject to corrosion (would be considered a type I anodizing). not for use on items that will see 80 degrees C or higher, as the anodizing will crack and allow corrosion.

Unlike Maryland, some of the ban states allow purchasing of pre-AWB standard capacity magazines. They are worth more to someone in Massachusetts than someone in Virginia.

G.I. mags are/were aluminum and they are all made to government specifications. There is nothing special about them regardless of manufacturer. A lot of people get taken advantage of by unscrupulous sellers who sell the G.I. Colt mags at higher prices. Note that there are some collectable Colt mags but, they are the very early production version and extremely few remain.
If you notice, the mag on the right has the Colt marking on the magazine body and the one on the left does not. Many people make the mistake of thinking that if the floorplate is stamped Colt, it is a Colt mag. This is not true, it only means the floorplate is of Colt mfg. In the service, we disassembled all of our mags and dumped the parts into a barrel partially filled with solvent for cleaning. No attention was paid as to which parts went with which when they were reassembled.

I remember that now that you mention it. I also don't remember ever seeing any marks on the mag body itself.
Oh well, I can only be sure that the ones I have are genuine USGI issued mags.
