Another super entry, my friend @lis!
And a hefty amount of extra goodies!
Looking forward to your build!

After you do this Tamiya P=51D, you should try the Airfix kit, which is better. It has positionable flaps and a canopy that's easier to pose open, and more detail in the cockpit. It's almost like a 1/48 kit shrunk down.

@tcinla Thank you for your informatons. I ordered Airfix kit too. Main problem is that I need aftermarket Areoprop propeller. Only Hassgawa had this prop in kit, but didn't have Dallas canopy and have less details in kit than another. I found propeller set for Tamiya. Also Pavla had Universal set of prop blades but unfortunetly was sold out and I didn't found it in other hobby shops. Tamiya had separeted pleksiglas imitation part of canopy. My first think was it will be more easy to build than one piece canopy.

Work with new Mustang get very slow because some reasons. Today I primed some parts to assembly cockpit.

Good start, Lis @lis

The interior green looks great, Lis @lis
For sure you will handle the parts with care, so that should not become an issue.

During thinking about how to fit Areoprop propeller I build pilot's seat with safety Belts from aftermarket set Eduard.
