  • Differences between versions were simplified with the adoption of the designation “M-41C” for all.
  1. Tests and Unique Prototype with Protective Side Skirts:
  • One unit was built and tested, incorporating 90mm Br2 and French super 90 cannons for experimentation.
  • Equipped with M-220 sight from Kollmorgen, laser, night vision, and Fernanti computer.
  • Protective side skirts were removed due to costs, planned for a future export version.

M41C super 90 was armed with an unstabilized Brazilian made copy of the French GIAT CS Super 90 F4 gun that they called it ‘Can 90mm 76/90M32 BR3’. The gun had a depression of -6 degrees and elevation of 18 degrees, it had a recoil stroke of 550 mm, as secondary armament it used a .50 coaxial heavy machine gun and was armed with a roof-mounted .30 for the commander (with 500 and 3000 rounds).

I do apologise for my stupidity, but for clarity could you tell me what nation this is from, I cant seem to see anything confirming its nationality?

only the gaijin can decide

no like what nation does this tank originate from?

I’m assuming its a south American one but is it Brazil, Argentina Chile, etc?

It is a tank developed in Brazil, it was derived from the M41C, it is a modernization kit for the M41, however the topic explaining the origin of the M41C was not accepted by gaijin

Seems like Brazil, looking into the company that developed it confirmed it as well.

The development of the M41C is a very interesting story, because in the 70s with the scarcity of gasoline and 76mm ammunition, they had to adapt the engine to diesel and the cannon to 90mm, so Bernardini made an adaptation transforming the cannons from 76mm to 90mm , so there was a variety of tanks with guns of different sizes

90mm APFSDS on an M41 would be extra fun. +1 for LatAm.
