Danzig Overprints

Could anyone help with identification of this stamp? Obviously, the surcharge is badly skewed (and incomplete). I can find nothing that it might relate to.

Hi there Canary, Welcome.

That does not appear to be a surcharge/overprint but
is part of the postmark. Winter....

Deutsches Reich, Wert 10 Pfennig - Freie Stadt Danzig

1935

Perhaps it is a precancel? Also, does anyone have a list of post offices in Danzig that had their own postmarks during the free state era?

Very grateful for the help. I guess I was just trying to make it too complicated!?

Some more interesting info on Danzig.


After the Paris Convention treaty had been signed by the parties concerned, paving the way for the necessary foundations been laid, accomplished and all conditions fulfilled, in order to proclaim the FREE STATE of DANZIG.

This proclamation took place on November 15, 1920, in a solemn session of the constituent assembly.
By this solemn action DANZIG became a member of the international community of sovereign states, representing a separate independent subject in accordance with international law.

Nevertheless, it has to be emphasized that the decision of the allied and associated great powers regarding DANZIG violated the 14-points-program of President Wilson that had been one of the cornerstones for the armistice between Germany and her former enemies.
