1931 Himmler signature original?

[Oberbootsmann]

Hello. I'd like to get some opinions on the document shown below. The signature looks good to me but I don't like the grammar and odd complimentary close of the document ("Mit Hitler Heil").
I've seen that on early Goebbels documents but never on Himmler papers.

Cannot comment on the greeting, but the signature looks ok to me.

This document is addressed to Gauleiter Hinrich Lohse in Hamburg and therefore the salutation is quite normal. The signature is 100% authentic. I have a good copy of it without the blacking out....a nice early SS document.

Thanks, Adam and Max. That's good news!
