Gentlemen

I follow this thread with great interest and am delighted by this latest photo courtesy the 57th Bomb Wing. If it's not too much to ask, may I ask for your insights into the colours found on this aircraft?

I'm not expert in the way you are, so please forgive my possibly elementary questions.
1) Is it correct to assume this airframe started it's life in Luftwaffe service? Is the underlying camouflage one of the various manufacturer's normal schemes?
2) The blue/grey overpaint of the Balkenkreuz as Chris notes above - looks to my untrained eye bluer than 76? Or might that just be the resolution of the film or screens we view it through?
3) It looks to me (does it to you?) that the oil cooler, the vertical stabiliser, and the panels in front and behind the cockpit are possibly all from the same batch of 75 as the fuselage band?

Many thanks, regards Don
