Can anyone tell me if this is a default font or if it is modified?

It looks hand-drawn to me or a pastiche taken from several fonts: The circle of the Q is not symmetrical, and the Q does not descend slightly below the baseline as the C does. The lobe on the tail of the Q looks like it’s taken from Lombardic initials. The vertical crossbars on the A and H are different weights. The E resembles Bernhard Modern, and the serifs on the E and C are different in character from the serifs on the other letters.
