[Lucky13]

This is supposed to be an early model Sd.Kfz. 232....

....what is the differences, that sets it apart from a later model, just the antenna?

The Sd. Kfz. 232 (8-Rad), which was produced from 1938 to 1943, was a 231 with additional medium range radio sets and a large frame aerial. From 1942, a small Sternantenne (star aerial) replaced the frame aerial, a modification retrofitted to older models. The official name was schwerer Panzerspähwagen (Fu) Sd. Kfz. 232 (8-rad).

Maybe useful, to make it an later model?
