You are right, in spite of my intensive search, in forums
and in books, have not found any information.
Right, wrong title not a Freikorps,from the motto can be a Regiments Erinnerungskreuz .
I have found, at various sources, 1st class cross with various attachments and the placement of the manufacturer's stamp in different positions.
On all crosses the manufacturer's stamp is identical.
IMO, that means different stamps have been used.
It is more fitting the are Muster Kreuze pattern crosses than fakes-fantasy pieces.
Why should one faker use several stamps?
It's just my personal opinion with no evidence.
Thank you very much ,for your time and opinion.
Regards,Jannis.
