Spanners at CX the A330 T700 dosen't have a sleeve, has the 4 buckets very similar to the as 340 illustrated.. Unlike all the other RR Big Fan engines in the 22B / 524 series that have a sleeve and blocker doors. The reverser is made by Herle Dubois on the 330/RR.
Reverser on the B777 is a Boeing design by Rhor I believe for ALL engines on that aircraft.
