UBB.threads Forums Edged Weapons Rohm Dagger Forum SA Dagger, need experts opinion

Hello experts.

I want to buy this dagger. It is selling with a Certificate of Authenticity. I only need the one Dagger, I do not collect daggers. This one is of course very expensive. Please look at the photos, what do you think? There is tool damage on the nut. But in the direction of securing the nut. There is black glue around the eagle or is it done with fire while attaching the eagle. What is this? I don't see any ugly wood-to-metal connections, it looks good is my opinion. Blade, wear is shown, I understand that it was cleaned and sharpened. The question is - is this the original acid etching or we have reason to think that they applied the Röhm signature and then cleaned the traces of acid on the blade after war? Does this dagger have a chance - is it all original?

Regards
Viktor
