Having done three Uprights, this is my first of two Grands, as the base game one is pretty awful and WAY over scale!
It is my impression of a Grotrian-Steinweg 140 made in 1970.
It should fit in nicely in most moderate sized rooms without taking over the whole place!
You can find it in the creative section of Hobbies & Skills
It cost $12,500
