I have been lucky enough to own four or five at this point. I have sold them privately in the 2k range.. I have seen them sell for more publicly. Mauser is the most common and HZW the least common. Menz and geco's I think have also been reported. HZW and menz also provided scope mounts and small caliber pistols to the ss so the trainer collection makes sense. Mauser rifles show up I think cause of the sheer volume of dsm34's they made. These were probably purchased privately anyway with no factory preference.
