RBailey, I plumped in this one and I see you have been generous with hints.
So we are looking at:
- first flight on November 11, 1918
- name of this machine starts with an A
- this BIPLANO was the second design of this designer, the first design being a MONOPLANO
- probably this designer made other machines after 1918
I assume we are looking in at an Argentine, Brazilian or Mexican plane.
Cheers
