C-87 Liberator Express + AT-22 (B-24D)

[airdave]

So, I got this request for a "memorial" model.
The family of a WW2 hero who flew a number of different aircraft,
and trained to fly B29 bombers near the end of the War.
The facts are sketchy...as far as what he flew in, what he trained on, where, when,etc

but in the end, I have agreed to do a "fantasy" B-24 in the form of a C-87/AT-22
with various markings and artwork representing different aspects of this Pilot's career.
This will be a one-off just for them.

But first...
I have to create a kit of a C-87
(from that I can create an AT-22, the B-29 Flight Engineer Training aircraft)

The C-87 Liberator Express is the "transport" version of the B-24D.
There are a few differences, but mainly just a modified B-24D - armaments and Turrets removed,
nose and tail fairings added, nose Cargo door and left side fuselage cargo doors added.
A floor was added in the Bomb Bay area, seats and windows to accommodate about 3 dozen passengers.




I am still trying to locate a photo of an AT-22.
The AT-22 is variant of the C-87 aircraft...only five of which were produced.
I am under the impression that all differences* (from a C-87) are interior.
*to accommodate Instructors, training equipment and trainees.

But I would really like to confirm any visible exterior differences by seeing an actual photo.

...
The C-87
I have completed the two major modifications of the B-24D model by altering the Nose and Tail sections.

I have to send out big thanks to Gary Pilsworth who created the basic 3D models for the new nose and tail fairings.
For some reason I really struggled with my first nose redesign....and combined with too many other projects on the go,
I just couldn't get going on the work. So I reached out to Gary, who I know does great 3D model work, and he graciously
helped me with a simple, but well designed three part template for each modification.

Just a tweak here and there...add some texture and colour and surface details...and there it is.
These are the two final test builds of the new nose and tail parts.
Not sure if I will build the entire fuselage, but this confirms what I needed to know.




I have got most of the B-24 kit converted over to "bare metal" finish
and I have also added the new parts.
Next job is to update the Instruction pages
and then make sure all uneccessary parts are removed from the kit.
eg guns, turret parts, bomb bay details, etc

I plan on producing a US version as depicted in the first photo in this thread.
In fact it will be 44-52987

I will also do this BOAC version (shown below)
Apparently plenty of C-87s went to England for use in Ferry transport across the Atlantic and into northern Europe.
BOAC airlines bought a few for their civilian transport efforts.
So I think that will make a cool model with the RAF insignia and BOAC logos.



Reminder, if anyone comes across a photo of one of the AT-22s, I would love to see it!

Outstanding project.

Always nice to see collaboration among paper model designers.

Another variation was the C-109 tanker used to support the MATTERHORN operation (B-29 bomber offensive from bases in China)? However, I believe the the C-109s were converted from B-24Js and, therefore, were different in appearance from the AT-22 and C-87. This MIA recovery-related page has many images of aircraft lost flying the Hump and includes a low-resolution scan from the Squadron/Signal pub on te B-24 that shows what the C-109 looked like.

This is a great idea Dave (also a thanks to Gary P.), the nose looks fantastic. I look forward to the development, and release of the BOAC version.

This is a long-time dream of mine, the C-87, and I am really looking forward to one of these, not least the British one. I believe one of those visited Sweden (have to look it up) on regular courier runs or repatriation tasks. It was considered for the first Swedish modern (for its time) airliner, but the eventual choice became the B-17s. Even so, I'd like to work on a fantasy version of the C-87 in ABA livery, similar to the SAAB conversions of the B-17.

So, count me in for a purchase.

[airdave]

I am very glad to see there is interest.

But can someone find me a pic of that blasted AT-22? lol

[Don Boose]

I forgot to mention, I will buy one, too.

The B-24D really made a nice-looking cargo aircraft. Most bombers look a little odd when they have been demilitarized, but the C-87 (and, presumably, the AT-22) really looks quite attractive to my eye (not so much true of the C-109, which looks rather lumpy).

PS: No joy on AT-22/TB-24D images, but found this photo by Larkins of a TB-24L Serial 44-9630: http://www.aerofiles.com/conso-TB24L.jpg Unfortunately, the TB-24L was a modified C-109, modified from a B-24J airframe, so no help in your current search.

This site Consolidated RY-1/-2 Liberator - Warbird Photo Album has a picture of what it calls a RY-2.
It is proving to be very difficult to find a photo of an AT-22 aircraft.

[airdave]

Still no luck finding a photo of that elusive AT-22!
At this point it is mainly just to confirm the exterior colour(s) and any specific markings.
I have pretty much confirmed that all modifications from the C-87 base aircraft
are internal mods...seat and berth removal, installation of equipment and Engineers stations.
Basically turning the inside into a classroom for half a dozen Flight Engineers.

But... I have finished all the fuselage modifications to the C-87
and just have some artwork to clean up.

I tried to assemble the fuselage over the weekend.
And this is what you get when you watch TV and don't pay attention to what you are doing! lol



Granted, I haven't got the most experience with building the B-24 in its entirety.
Yes, I have built every single section and area of the model, but I 've never put them all
together into a full aircraft!

This B24 model uses a "thru-the-body" wing assembly and requires a 3 part Former assembly
that goes in the middle section of the fuselage.
I was rushing...and not paying attention...and fumbling and forcing things together...
and finally I wrinkled (and ripped!) part of the forward section.

After that, I crushed the Tail section where it connects!

Too lazy to build new parts, I trimmed, and smoothed and glued until it was all together.

In the end its passable for a couple of photos.
The goal was mainly just to check artwork as well as Nose and Tail assemblies, so all is well in
those areas.





I have to tweak the side Windows...move the row a little bit and re-align them all.
And I need to try a different "astro-bubble" window on the top.
I don't like the shape of this one.

I do have one question...I can't decide between the plain black window
or the gradient colouring, which represents the glass windows.

Obviously clear windows could be installed using plastic, but thats a builder's option.
If left intact, would you prefer the plain black or gryed look?

[Don Boose]

Beautiful airplane!

I like the gryed look for the windows.

Looking good, watching this project intently.
