Probably got their brushes mixed up with the SdKfz 232 8-rad...
However, I got it wrong too, as it's the 234/3 (with the short gun) and 234/4 (with the longer gun of the PaK 40) we are talking about here.. not the Puma (234/2)... Less than 100 of each /3 and /4 were produced, but again only from 1944 (/3 & /4) and into 1945 (/4). So they still did not make it on time for any fighting in Africa...
Sorry about that.
