HP2 brake conversion Doku registration

Hello community,
I'm going to write an ancient theme:

Is still active here someone who has entered the HP2 conversion and possibly. from the acceptance still has the report or at least the vehicle certificate with registration?

Yes, I know that already in the "good old days" the opinions about the necessity of registration was generally much discussed, because it probably also the HP2. ETKA at the V8 etc. - I don't want to chew that again.

I'd really only be interested in whether someone entered it and maybe sent me the documents. I also know this fax of the safety certificate - but today I do not think that someone with this document without a letterhead etc. - at least not without e.g. a copy of the Fzg.-Schine etc.

Best regards and a good start in 2023.
