L1011 and Caravelle
The Caravelle used the Lear Seigler system, according to the 1967 reference above. I don't know about the L1011. Unlike the Trident and VC10 systems, the Caravelle system was single-lane, with the pilot as backup, which might explain (because of the reduced complexity) why it achieved certification earlier. The descent guidance on the Caravelle system differed in an interesting way from the British system, again as explained in the 1967 article.
