I didn't want to necropost, but found some info to update the knowledge of wood type in Rossi R92 rifles.

I dot´n find the exact translation of Brazilian wood names, so I will use the Brazilian and scientific names.
Rossi used Guajuvira wood (Patagonula americana) up to 1990´s.
The wood was changed later to Açoita-Cavalo (Luehea divaricata), "horse whipper" in a direct translation. This wood is also used on IGA-Stoeger shotguns and, in the past, to make replacement stocks for military rifles, like our Mausers, Garands, and .30 M1 carbines.
CBC/Magtech used Imbuia (Ocotea porosa) up to 1990´s.
According an retired worker of Brazilian gun industries, Brazilian hardwoods has many tone variations, and some American customers does not liked to receive a gun with a different stock color of seen on showcases. Luehea divaricata has an uniform color and almost no tone variation.

I found translations for Guajuvira (Brazilian Hickory) and Imbuia (Brazilian Walnut), but not for Açoita-Cavalo.
Just to add to the discussion of what type of wood was used in Rossi R92 rifles.
FWIW.
