Common knowledge in the US is the 512TR had only 5 luggage pieces vs the Tesatrossa's 6 pieces. My research points to this being generally true, as the long piece did not fit well behind the US-spec seats. It was offered in limited numbers in Europe, though generally you also only got a 5 piece luggage set in Europe too. After over a year of searching I found the long luggage piece made for the 512TR! It is in excellent condition considering its age/rarity. Please images below/attached. Tragically it is the wrong color for my needs, but I just had to get one of these in the US in my hand and prove it was the real deal!
