The early 707s had a "spade" type of nose gear door that hinged from the rear and covered only the strut. Late aircraft had the double side-hinged doors seen in the photo you linked to. See the 707 guide for details.

It's best to study the Ultimate 707 guide to make certain which version you want to do. From everything above, I'm betting that the Airfix kit wouldn't be too far from wrong. You'll need to alter the nose wheel doors, and make the "organ pipes" longer so they look like JT-4s.

Yes, but be careful which Minicraft kit you get; some of them also had Conways. Look for the Northwest boxing if you can find it. The military boxing of the VC-137 can also be used. There's a minor problem with the Minicraft kit though. Its cockpit section is much too bulged. You can get a corrected nose section from Two Mikes resin.

Correct markings available here. There are also several other options in the list.

It's amusing to see a 5 year old post get so much attention

One of my classmates in the Navy was named Derek Moss. He swore up and down that if he ever had sons, he would never name them either Christopher or Peter.

I did the Williams Brothers 1/32 C.450/460 and that was small enough. Yours is decidedly tiny!

What scale will it be?

Isn't that when a whole bunch of triffids goes past?

It's kind of like a Bulldog. It's so ugly it's gone back into the cute territory. This is especially true when you consider it's only about as long as your finger.

Something about the old joke regarding screen doors comes to mind... Or perhaps it's Leonard of Quirm's Going Under The Water Safely Device?

Now if only some brave company could do a kit of that...

And with the bear trap, you have help pulling you down, and a seriously strong piece of machinery which clamps onto a probe underneath the helicopter which keeps it from moving about once it's safely down. After all the folding is finished, the bear trap can move the helicopter into the hangar without any external aid.

Perhaps try a graduated fading with the prop disc? It should be slightly darker towards the middle of the blade position and thinner towards the edges.

No.
