Hi Spock,
the croos is not one made by the accepted makers. Especially , as my dear friend Mike already pointed out, the dipping ring is a big "no,no". This feature, i.e. the dipping ring, was only legitimate found on the Grand Cross so far - however, it must be said that there are contemporary pictures with seem to show a dipping ring feature. No such cross with 100% provenence has so far surfaced.
Your cross here is a fake.
