I think that you'll find that these "Embraer models" are actually Wesworld fantasy types.

Just to clarify, the supposed Empresa type numbers have been applied to existing aircraft. These were listed, in descending order, as:
Embraer EMB-28 (Seversky SEV-3XP)
Embraer EMB-29 (Hall PH)
Embraer EMB-31 (Renaud [sic] R.31)
Embraer EMB-32 (Renaud [sic] R.32)
Embraer EMB-33 ("FMA I-100 Baron" = Vickers Type 279 Venom)
Embraer EMB-34 (LACAB GR.8)
Embraer EMB-35 (Bellanca 29-90) [I assume that he meant 28-90]
Embraer EMB-36 (Seversky P-35)
Most of the actual types are reasonably well known. The author obviously has an affinity for fairly obscure Belgian aircraft.
The Renard R-32 was a one-off derivative of the R-31 recce aircraft. see: http://www.samoloty.ow.pl/fot/fot241.jpg (Gnome-Rhône version)
The LACAB GR.8 was another Belgian one-off, this time a bomber design. see:
