Thank you for your comments, mates!
So it looks like Eduard team was in the hurry getting the sprues out of the molds to pack and send this before the August 1st. Fortunately, there is no sink marks on the fuselage parts, where it could be a real problem taking into account rivets and other small details.
@tcinla Thanks Tom! The reason I was curios about that hand pump because you can build only one early Mk.I out of the two because of different fuselage parts in this dual-combo box. So the second one definitely should be for the BoB. Also, I would wait for your review of this kit. Let's call it "accidentally", but I've ordered another one "Spitfire story" box.
@j-healy I couldn't agree more, John – exhausts parts on the VIII/IX are over-engineered.
The paint job has started. Black and white fast recognition pattern is on the way.
