Do you recognise this throttle box?

I’ve been trying to identify this throttle box and failing miserably. Clearly it’s from a four-engined type but I’ve so far drawn a blank. The tops of the throttle levers resemble those on production Concordes, but the rest doesn’t match. I’m afraid I can’t provide any hints – I don’t know if it is from a civil or military type – but would be extremely grateful if anyone can put me out of my misery.
