@Walter Hinteler,
The so-called 'left wing' within the NSDAP was a very small group. (See my above posts, but I've got additional sources to back it now, too.)
re 'anti-capitalist' of the NSDAP, I came across a rather interesting detail:
in the Weimar Republic, the formerly governing kings, dukes, princes and all noble houses should have been expropriated ("Fürstenenteignung"); the question was 'how' (see: article 153 of the Weimar Constitution).
In 1926, a referendum was announced
The left parties, from Communists to Socialists and Social-Democrats as well as some left leaning Liberal parties had the opinion that such should happen without compensation.
(Source: [German version of] wikipedia ['Fürstenenteignung']
The more centrist parties and the majority of the Liberal parties opposed such ideas but were in favour of the expropriation in general.
Only the NSDAP with some other conservative parties opposed it completely.
Interestingly, they therefore called for the expropriation of the capilalists, naming and meaning here only bank owners .... Jewish bank owners.

NB: this advert equals the 'Jewish bankers' with the 'red leading mob' ("rotes Führer Gesindel") of the Socialistic International II and III.
