Hi Robinson,
You are refering to
FiSk 199 project, which actually was built around a Bf109G-1, WNr.14008 ... Not a Bf109G-2.
You can check on following photo
http://www.me109.info/display.php?a=e&fid=7032 the very small air scoop just over the super charger; typical for a G-1.
It wasn't a G-1/R1, neither G-2/R1.
Regards.
