It's not an ERLA (Leipzig) built G-10 this has a unique square panel on the port side just below the canopy rather than a curved bulge. so it can be depicted as a WNF Wiener Neustädt Flugzeugwerke or MT Regensburg version both having the bulged/curved fairings on each side of the cowling.
post some pics of the decals, soon tell you what they represent.
The kit is pretty reasonable for 1/72 scale....from a few shots i have seen of the sprues...
