Mismatch most uncharacteristic for you Tony. Lovely image of the Sheaf Mount though, I think this is when it returned to JLT for conversion. The ship was on shore power one day, and my enduring memory was of an immaculately kept, almost silent engine room where I had the great pleasure of having to split seven eighth, rusted whitworth nuts on a flange below the floor plates, to undo the flange. couldn't get a caulker to do it in a hundredth of the time because it was a fitters job, not a boilermakers!. Thanks for posting the image.
EDIT - title corrected
