Yep that is the correct unit. Thanks, I will investigate further. I always thought I was quite meticulous in completing my log books, but I’ve a few ‘holes’ in Gnat serial numbers. As to that serial reappearing - no chance! I didn’t ‘shine’ at TWU so only did the ‘short course’!
i have checked and XG 196 is/was an F6, I do remember that I flew a FGA 9 first. (I also realise that I had checked this serial previously - just in case).
