I have to correct myself again... the AGDZ was an 8x8 heavy recon vehicle, also taken over from Austria in '38 and mostly used against Partisans; similar in configuration to the german 8-wheel recon vehicle, but quite old-fashioned-looking. - check those very good pics of ADGZ in use with SS, on a polish website:

The other vehicle with the track/wheel changeable confiuration was called Saurer-RR7 and can be seen here:

wiki info:
http://de.wikipedia.org/wiki/Saurer_RR-7 - it says it was sued as a armored observation vehicle and not more than some 140 were produced in total, 12 ordered originally by Austria and the rest by the Wehrmacht.
