The first case I can remember reading about
is during the Allied invasion of N. Africa, when P-36s flown by Vichy
French were encountered, but it seems there must have been previous
instances -- WWI, interwar, or earlier WWII.

Yep, the Wildcats fought the Mohawks (H-75s to the French), along with
a few A-20 Havoc types (DB-6s to the French).

Somewhat similar, the Finns flew Brewster Buffaloes against Curtiss
P-40s and Hawker Hurricanes, though of course there were no Americans
(or Brits) on either side. The Finns sometimes replaced their Wright
Cylone engines with Russian-built copies of the Cyclone, then flew
them against their former owners.

In February 1942, the Japanese army 64th Sentai captured two
Hurricanes in the Dutch Indies and flew them to Thailand, intending to
use them on spook raids against British bases in Burma.
