Diamond Lil is actually an LB30...in fact, if the info is correct, it is the original LB30 that was turned into the C-87 prototype.
But it has since been been remodified back into an LB30 (B24D).
.......................
Anyway, I have not found anything else on the AT-22.
So it seems there is no reason to assume that the outward appearance of the AT-22s is anything different from the C-87s that they were made from.
In other words, the modifications to the C-87 were all internal...Flight Engineer stations (six of them) and facilities for the Instructors and crew.
.........................
So...
I have a C-87 package ready to upload and list.
AND...I have an AT-22 kit ready as well!
Just got to get the files uploaded and the store listings done.
...........................
I've also got a third kit done that I will release shortly after.
Remember that BOAC plane I posted earlier?
I thought it would make a great candidate for another model.
Well, seems this is not a C-87 Liberator Express!
Its actually one of many LB30 (B24A) Liberators that were produced as Transport aircraft
with similar modifications to the C-87.
(No guns, turrets, bomb bay...new nose and tail...modified for supply and equipment transport.)
Unlike the C-87, they don't have passenger seats or passenger windows,,
just some porthole style windows down each side.
...they also didn't have the large rear cargo doors like the C87.
(a smaller set of cargo hatches were built into the bomb bay area.)
Anyway, many of these LB30s were lend-lease to the RAF for supply and transport.
And the RAF hired commercial companies like BOAC to crew and operate the planes.
A lot of these planes went back to the US, and then were repurchased by civilian companies
to continue their work after the war. Even though the war had ended, the work had only just begun.
Anyway...I will also be releasing this BOAC AL507 (LB30)
and I have one more C-87 in mind.
And I have to finish the "memorial" plane I promised to a private customer.
