LO2x was everywhere until late 1990s.
103 used to have LA till Tibs hto.
I dun think e VO3x on 82 disappeared immedately aft NEL
commencement, 82 in fact had pretty good freq until it was
rationalised.
And 136 had LO2X into the early 2000s.
Soon after 136 lost the LO2X, in the NE region, it was 165 next
that lost the 0305s and the VO2X, while 74 held on to its 0305s
till they were scrapped.
That's what I can remember.
