1. Only a few of them produced, but all the ones that were manufactured were used by the one service that acquired them.

2. Some were civilian aircraft converted to military use, others were built specifically for the military, though based on civilian aircraft.

3. Twin engines, crew of two.

4. A trainer, but some of them were used in other roles.

5. Strictly speaking, it might have been more accurate to say "looking for a class of warbirds," because there was a fair amount of variation among the less than 30 of them used.

6. One of them played a minor part in a very-well-known operation and the major role in an incident that still remains somewhat mysterious.

7. A portion of one of them is (or at least was: my info may not be up to date) on display in the Smithsonian Air and Space Museum.

8. A portion of one of them ....

9. The only military user was the navy.

10. The "very-well-known operation" referred to in clue 6 was the Doolittle raid.

11. Their main use other than as trainers was as patrol aircraft. The one now (partly) in the Smithsonian was used in that role. In Ohio. Really.
