eBay is your best bet for that, considering most people think Prussia = Nazis. It's inaccurate as hell (the Prussians reeally didn't like the Nazis for various reasons), but people still think it.
A huge part of that is because they have spent some time as the same country; "The formal unification of Germany into a politically and administratively integrated nation state officially occurred on 18 January 1871 at the Versailles Palace's Hall of Mirrors in France. Princes of the German states gathered there to proclaim Wilhelm of Prussia as Emperor Wilhelm of the German Empire after the French capitulation in the Franco-Prussian War."
There's also how Hitler took control of Prussia; "Ironically, two of the penultimate measures Hitler took to consolidate his power violated the Enabling Act. In February 1934, the Reichsrat, representing the states, was abolished even though the Enabling Act specifically protected the existence of that chamber. A few months later, Hindenburg died, and Hitler seized the president's powers for himself in accordance with a law passed the previous day. However, the Enabling Act specifically forbade Hitler from tampering with the presidency. By this time, however, Hitler had become law unto himself, and no one dared object."
It's quite logical to make the connections between Prussia & Nazism.
