The Sapphire
Tankertrashnav, guess you were not on the early Victor 1 when we had the "centre line closure" problems with the Sapphire, not fun but resolved with the abrasive coating put inside the compressor cases to just scuff the tips of the blades to give a bit of clearance, I remember it well having to jack up the wings to get the engine doors to crutch up after many engine changes, I still have a couple of engine door bolts in the garage just to remind me what fun we had !!!!
