1. First flew prior to 1920
2. Twin V-12 power
3. It had predecessors; a small number of experimental prototypes and the first production version (>100 made) used up the first two model numbers
4. It floats (intentionally)
5. Post war served in forestry patrol among other capacities
6. First aircraft to fly from Portugal to Madeira
7. Had 4 machine guns and just under 1000lb bomb load.
8. Took part in the first transcontinental flight in my home country, which was staged in several legs (no non-stop back then). It flew the leg from Quebec to Manitoba. The exercise was to look at practicality of mail delivery by aircraft.
9. The engines were Rolls Royce Eagles (20 litre I think), the aircraft specs say the VIII 360hp model, but the VIII was 300hp and the IX was 360hp so might have been the 9's. Close enough.
Hello? Maybe this is a tough one, but there were nearly 200 built.
