Well, well, well none other than General Galland

. I see you moved to Canada no less

. As far as construction goes no other info I can think of. The 190 is question is from Einsatzachwarm of Jagdgruppe JGr. 10. the work number is unknown. This was a special weapons and tactics unit of the luftwaffe. There are at least one other Fw190A-8 with the snake on the fuselage and thats "red 11". The info I have indcates it had "factory standered" stenciling, but from the pics I have I could see none at all.
like wayne little said the snake is a 3 part decale. The head on the engine cowling, main body between that and the fuselage cross,And finally the tail from the Cross back. It also thin and a real pain to get into correct position. Which if you screw it up thorws off all your other marking. I would not recommend it for the novice modeler.
The pilot is listed as R. hartkopf, I'm sure I had found info on him in the past, but now can't even find his name in the luftwaffe pilots list
I can't think of anything else off the top of my head. I built it in large scale with those marking just because I thought it would look cool. I sits in my living room on a glass table and makes an excellent conversation piece. The most commonly ask question I get is "did they really fly it painted like that".
Thanks for the comments guys. All comments and critque welcome.
