Well, for a good start...
I've made these two quite some time ago, for a project that I've shelved in the meantime, and later nearly forgot about these drawings.
Yordanov-1 was Bulgarias first aircraft, flown in 1915
Nielsen & Winther AA was Denmarks first (and I believe that also: only) domestic-built fighter plane, flown in 1917 and built in short series of 6.
(I hope that Thiel will forgive me this encroachment of His territory
).
