Helmut Wick feldpost letter

[harri109]

Here is another recent acquisition from Germany, which I thought members might be interested to see. It’s a Feldpost letter written by Major Helmut Wick to Major Hennig Strumpell on October 20th 1940.
The day before, he had been promoted to Major and Kommodore of JG27, a decision he was obviously not happy about. Wick took over command of I.Gruppe JG2 from Strumpell on September 9th 1940, who transferred to a fighter school. Ultimately Goering reversed the decision and promoted Wick to Kommodore of JG2 on the same day this letter was written.
I would be interested if any members know what the four letters followed by Paris represent on the reverse of the envelope, JG2 feldpost office maybe??
The rough English translation of the letter is as follows:

Honoured Herr Major(Strümpell).
For the congratulations and the kind lines I ask Major to express my most obedient thanks.
Unfortunately I was made Kommodore of Jg27 and Major.
Since I thought this solution was wrong, I took the opportunity yesterday to talk about it personally with the Reichsmarschall. Sperrle and Jeschonek were there. The Reichsmarschall still reserves the right to decide on this question, which generally concerns the entire hunting industry. I hope it falls soon.
In the hope that I may continue to retain the inheritance of Herr Major.
Entirely devoted Wick
