you can debate for hours and hours on what the correct OD would be, and we'd still disagree with eachother :-) :-) :-)

Fact is: we don't know what the vehicles looked like during WW2, and pictures generally give you some idea ( if you have the luxury of a color picture that is ).

Even then, different batches, different time of eposure to the elements and human factors can contribute to the fact that a vehicle could totally look different from the next, even when that was build in the same factory on the same day.

My advise: go with what looks right

I use Games Workshop Catachan Green. Its green and looks like OD..

yep the war dept.. and army procurement had the correct paint chips....... the factorys prob had some too... make the paint.. call a batch close enough....... sent to the units.. they get it after its been stored in who knows what conditions for who knows how long........

they open the cans...... whatever shade of green it was they used unless of course someone sent off to the states for the paint chips ..."just to make sure"

War Dept. says "And YE shall make it OD GREEN" Fine, no problem.

Now. Vehicle plant in Calif. gets OD green form thier local Gov supplier. He has one formula

Vehicle plant in Mich gets OD green from thier local Gov supplier. He has another Formula

Vehicle plant in Alabama gets OD green from thier local Gov supplier. They have yet another formula

Now self same "local goverment supplier" also supplies OD green to the AAF which want thiers a different shade of OD green. and the Marine Corp has thier particular color pref

one manufacturer may have added a bit too much green, where as another may have had not enough. During the war, they may not have had the luxury of making the exact color OD.

I lived on tanks for three years, all you rivet counters and guys that look at your little picture books, call others names, and argue points, well I won't get ugly here. But emphatically yes there are variations in shades from one can to the next.

Don't forget to throw the "modern" variation of OD into the mix.

In a Military Modeling magazine of a few years ago, Steve Zogala (spelling?) wrote an article on US OD. He cited sources living and archival. In it he said he wrote about US dark green on WWII AFVs years before, and that he was wrong--it didn't exist. But to the point, he included a matrix of all the various ODs out there and wrote how they compared to USA's, Smithsonnian, etc., samples of WWII OD:

Model Master's FS34807 is THE closest match in his research.

Tamiya's OD is the best match for post-war OD.
