I didn't know there was more then 1 non-zimmerited or even un-camouflaged KTs, never seen pictures of them. Interesting, though most of my research has been confined to North Afrikan and Initial Production Tiger H1s.

Dunkelgelb was not the only base color. There are several websites that explain when Olive Green (RAL 6003) was to be used as the base and a time before that where the red oxide primer shown through as a replacement for RAL 8017. A quick google using these RAL numbers will light the way.

I do not agree that Tamiya has the best selection of acrylic military paints. I think Xtracrylix and Polly Scale do. I used Polly Scale, Tamiya and Model Master since I was a kid and when I re-entered the hobby. Now I prefer Xtracrylix and Polly Scale as they don't smell, thin great with distilled water and have a large selection of colors available. Another thing is that they're not Tamiya acrylics! Too many tanks look the same because they all use the same paint. They're not spot on matches either. You see a lot of mixing to match historic color swatches whereas some other brands are even closer.
