A rather elusive mfg/date, rare if the condition were there. Its worth picking up even mismatched like this...
People argue when the Republic died, but arguably it was in 1933 with the enabling act, certainly by the time Hindenburg died in August 1934, - Hindenburg was the last possible escape from Hitler, as bleak as it was resting upon a senile man surrounded by opportunists, the Army was led by cowards or men affraid of the youth in the Officer Corps. The eagles are similar to Republican era eagles, but different in style, - they are not similar to Imperial eagles, other than the symbolic use of a eagle.
Typically, collectors call these early NS eagles ("nazi" another ignorant application of a label, authored by the leaders of the German resistance in exile, most of which were far left themselves, - like national socialists themselves... the far right foolishly collaborated with the national socialists during the crises that lead to the fall of the Republic, but they were radically different and had very different support among the populations, - the national socialists appealed to the disenfranchised youth, colleges young men in the military, and later the working class, not to the propertied class/aristocracy and middle class in general. Only in NS fervent nationalism, and to some in the far right who were antisemitic, was national socialism acceptable, and this primarily due to the hostility/fear the far right had to communism, which although both national socialism and totalitarian communism were near identical, the "nazis" at least allowed the facade of private property and didn't mass murder the propertied classes and middle class... that was the only real distinction between nazis and communist, in every other meaningful way people were property of the state with no inalienable rights, something this country is headlong on its way to experiencing) Weimar eagles, but they are "nazi" because Hitler's reign of terror began in 1933 and the last vestiges of the republic died with the enabling act (and the only honorable men to oppose it were the SPD, many of whom paid with their lives.. and I despise the SPD, but at that moment they stood up to Hitler and were the last to do so... though to be fair to the KPD/communists, they were excluded in the same fashion Spanish left/communists excluded deputies when they illegally seized power in Spain)
