The One-Elevens I worked on:-
Most had Collins 618M VHF comms but I saw a few with King KTR9000s ? I think.
HF was Collins 618T if fitted.
The VOR/ILS nav fits were Collins 51RV1 or 2 on most I saw.
Marconi ADF receivers.
Autopilots were by Elliot except the 510s for BEA.
Flight directors were Collins FD105 or 108 except BEA.
The Oman AF had Canadian Marconi Omega nav. when new.
A few VIP ones had Litton 51 or 71 INS
Marker receiver and Transponder by Collins.
Weather radar Bendix or EKCO
My memories.
Dixi.
