Academy Bf 109 G-6 (3)

meanwhile I am still wrestling with my Academy G-6 - having trouble getting the exhaust staining looking right in this small scale - already wiped one attempt off - and the spinner spiral is a nightmare. I'm hoping this will be Heinrich Bartel's 'Red 13' 'Marga' - but so far I have been unable to find out if his a/c had white wingtips or a trop filter..
