But it probably didn't have a cast-iron frame though.

SWMBO'd has "collected" two upright pianos here. One timber frame the
other cast iron, the timber one is the heavier. That maybe down to
the timber framed one being older so has a much better built case,
even so it does have about 6 x 4 to 5' long 6x6 ish timbers in it...
