Only the early Bf 109Gs had a retractable tailwheel and even these got got a fixed one sooner later because the wheel was too small for soft surface and larger one replaced this, the new one being too large to be retractable. Most of the FAF G-2s had fixed tailwheel allready when delivered (even the new ones), however, there were still some with retractable tail wheel. The AH skins are the MT-201 which had fixed tailwheel and MT-222 which IIRC had a smaller recractable tail wheel.
