The think is with 3 projects, it would make sense to pool resources to get a batch of hubs/props done at at the same time, like was done with the recent Mk1 Spitfires, but, it would still be an eye watering bill.....!!
With so many modern abilities like 3D scanning, CAD & manufacturing techniques etc I'm still surprised that custom work like this is still so rarely done but TBH, it's not something I've much experience with.

They did it with an old car engine last year to get the last one of these cars going.

It's getting it done and certified that is the issue with anything that is going to fly.

Yep, and a lot of that depends on being able to prove that the materials used are equivalent. The alloys used to do 3d printing are not necessarily the same as those used in the original part; and the grain structure of 3d printed parts will be very different to forged parts. It's not just about making a part to the same dimensions from the same base alloy family.

I'm sure that this will be a recreation rather than a restoration. I hope they can pull it off.
No different to the recent trio of Mk1 Spits that have be done recently - virtually a new build built around the data plate dug out the ground.

A hell of a lot of the P-51's/F-4U's etc currently flying are pretty much the same.
Or the Mossie that is being recreated at the Yorkshire Air Museum from bits of this one and bits of that one.

Not there anymore.......;)
Its been moved to East Kirkby to join Just Jane, but it was at the time the only way of rebuilding what was (mostly) as last surviving NF.II Mossie, and given it can't ever fly, it can be rebuild using as many scattered original parts that can be collected as possible. Its been an amazing project by Tony for all these years.

Can't ever fly? Didn't know that. I saw a chap who must be Tony spannering one of the engines a couple of years back.

Yes, that's the ultimate aim, get it in a taxiable state, which if you followed this project since Tony started it many decades ago, will be a remarkable achievement.

Sea Hornet update
From Classic Wings Magazine FB page

"HERALDING THE HORNET!

A few months ago we were given the privilege of being the first to announce to the world, a new initiative to rebuild the world's last remaining substantial example of the de Havilland Hornet fighter, in this instance, the Sea Hornet, F.20, TT193. We have since visited with Paul, Steve, Marty and the team at Pioneer Aero and been amazed by the sheer bulk of Hornet airframe structure and materials that have survived. In addition, when Classic Wings announced the new Hornet initiative, we requested leads to additional parts and materials, and happily more Hornet and Sea Hornet items have come to light as a result, from several sources around the world, and are now with Pioneer Aero at Ardmore Airport, Auckland. We'll go into more detail on this in the next edition of Classic Wings but in the meantime, here is a great old period photo of two Hornets flying with 80 Sqn., RAF out of Kai Tak, Hong Kong in 1954. There's no question that the Hornet is one of the prettiest fighters ever created, so we can all look forward to seeing that shape emerge from the Pioneer Aero shop at some time in the future!"

I found this...



...on a Google search result for images of a Sea Hornet.

Didn't know they kept the 303s thought they were deleted for the radar gear...

It’s an NF Mk.2 (Night Fighter) version; all 8 guns were retained as well as the air intercept radar.

I understand what it cannot legally (and probably safely) fly, but could it technically fly?

Did the NF version have those bloody great bomb bay doors?

Yes, they gave access to the 4 x 20mm cannon.

Bomb bay doors are still there allow access to the cannon which fill the front half of the bomb bay. You can see the holes for the spent links and cartridges cut into the doors.

And of course you can now see 3 complete aircraft at the de Havilland Aircraft Museum.

As dr_gn says that's a photo' of an NF Mk II which carried the AI Mk IV Metric wavelength radar. You can see the arrowhead transmitter aerial on the nose; the receiver dipole aerials were carried under the outer wing sections.

When the AI Mk VIII Centimetric waveband radar became available the aircraft were fitted with a 'thimble nose' (Mosquito NF Mk XII onwards) and the Brownings were removed.

Do any other actual prototypes of WW2 aircraft exist?
