Did the Oviedo 93 7x57 Mauser use a hinged floor plate? Mine has one with the release on the side of the trigger guard in the form of a flush cupped button. I can't tell if it is factory or well done custom work? The trigger guard bow is streamlined. I owned one 40 yrs ago and a Orbendorf Turkish 93 20 yrs ago and I don't think they had it.( I don't trust my memory) Best, Thomas.
