Negative. K&T was used up until almost 1950 in rural areas and actually was
overlapped by the early romex. The house i grew up in was K&T and was built
in '45. The house I'm rebuilding right now was wired in the early '40's and
has cloth romex. Not a knob or tube in sight. Google 'knob and tube' for
more info than you want to know.

Knob and tube went out before the 1940's in almost all parts of the
United States which is where the OP is from, I think.
