It is sort of original - sort of in that I see it has the Sprague name on it, so it is a replacement for the original Philco part.
This cap and coil combination was intended to act as a wave trap at the set's IF frequency, 455 kc, and to shunt stray IF currents to ground.
You can read more about it on Chuck's site.

In replacing this part, you can either replace it with a 0.22 uF cap and not worry about the wires wrapped around it, or you can wrap a new wire around the new cap if you wish. You will see how it should be wound when you undo the original.
