Great work and terrific story as well! I actually have used hair as an antenna in the past too - very resourceful!
LOVE what you ( and Brian too ) are doing with your Portrait's and the ability to make whatever markings you need is a real draw.
I hear you on the HGW wet transfers. I ordered a set, and then heard basically what you experienced - they are kind of hit or miss. When they 'hit' they are amazing, but just as likely not to work out. But your bird looks amazing (and esp dirty - nice job!).
I do have two Eduard 109's in my stash, a G-6 Erla weekend edition and the F-4 Profipack, and even acquired the necessary Luft colors for them. We'll see when I get to them, but your really nice 109 piqued my interest for sure.
