Is that you and me Robo? Love that pennant!

Nice little Czechslovak badge on you there. Are you now flying X for X-Ray? That would give you an authentic serial #, I couldn't find an R for Robert used by No.501 unfortuantely
I'm really sorry but I forgot one tiny detail though, I have some noseart for my bird but it's no probs if that a pain - my fault, I forgot to add it. Will dig it out when I get home.
