Vallejo number 70.614
The first bottle was OK but the second had hardened paint in the bottom. I thought I could stir it up like enamels but no such thing. Once that acrylic gets hard stirring just breaks it up into little pieces. That's why there's little bumps in the final paint layer.
Actually, there's a few different IDF colors depending on the time period. Vallejo, Hataka and Tru color are a few that have their own paint sets.
