Hello Joao, 13 years later...

This great website on the Ju 52 says:
D-AQAR (W-Nr 4055) '... 31 Dec 1936: 1571 flying hours , Syndicato Condor, 25 July 1939: arrival in Junkers Leipzig workshops for overhaul , 3 Aug 1944: transferred by RLM (German Air Ministry) to Lufthansa as 'W. Höhnendorf' refitted with BWM 132.'
Clearly the record is incomplete. It is not clear to me if the sale to Condor is meant to be in 1936 or 1939. Especially if it was 1939, it is very doubtful that the aircraft ever went to Brazil since a return to Germany during the war is very unlikely.
The site doesn't say anything about D-2588 'Rudolf Kleine' going to Brazil. It was in Europe in Feb 1934 and Apr 1934 and became D-AHIH mid-1934, so it seems very unlikely.
