I have an idea that Ferranti suggested its use as an IF amplifier stage in the data sheet or application notes for the device. At 465kHz it should work well.
But the subject of this thread... no I have never come across a piece of Production equipment which used the ZN414 either!
I have of course made a couple of radios - one fairly small, matchbox-type, and another, loudspeaker output, which I mounted on my bicycle (incidentally, mounting INSIDE the triangular frame really killed the sensitivity due to it making a large shorted turn right around the ferrite aerial, so it had to go OUTSIDE).
