I can excuse myself for not recognising the knobs, but not for failing to recognise the chassis (although I can now, now that I know what it is) . . . Mind you, the last time I saw a naked chassis of an HRO must have been over 20 years ago, though. Moreover, it is somewhat comforting to know that I am not the only one who has stripped down a HRO: clearly a crime in certain circles I could mention. Perhaps we'll meet in the afterlife: a special branch of Hell, where will be forced to spend Eternity re-building and re-aligning HROs!
