A few posts back, someone asked what we thought of the B23...
IMHO...
The Douglas Aircraft Company designed and built many successful aircraft for the Allies that served with distinction throughout all theatres of operation during WWII. The B23 Dragon was not one of them.
Like the 4 year old B18 Bolo it replaced when first built (ff July 27, 1939), the B23 was a victim of rapidly changing technology, accelerated later by the demands of the war. It was more or less based on the Douglas DC3 airliner.
As I understand it, one reason why the USAAC ordered any B23's was the price: At approximately $ 133,000.00 it was about half the cost of a (4 engine) B17 Flying Fortress...they could buy more B23 aircraft as a result. That comparison is really an apples and oranges thing, but, a full discussion of congressional appropriations in the 1930's is another whole subject unto itself.
I believe only 38 B23's were built and the more advanced North American B25 and Martin B36 (and yes, even the Douglas A-26) relatively quickly proved to be much more effective twin engine combat aircraft.
The B23 found several non-combat uses during WWII, including training and transport. I am sure that other WIX members could give you even more information about it's wartime service.
I have never spoken with a pilot who flew B23's and wonder just how well it handled (like it's relation the DC3/C47/C53, et al??).
Depending on which coast you live on, check out the examples at NMUSAF in Dayton, OH or Castle Air Museum in Merced, CA. Both are pretty accurate examples of the B23's military configuration. The NMUSAF B23 was in restoration as recently as last year (don't know if it is completed yet). The PIMA one is still in "civvies". and was not on public display two years ago...although you could just see it with a telephoto lens from the edge of the public area.
Not sure if this answers your questions or not...Hope it helps.
