I grew up on a new development which didn't get a bus service until years after we moved on so my childhood memories of buses are limited. In the town centre I used to notice Alder Valley's half-cabs (Lodekkas or Lolines?) as they seemed so old fashioned.
Probably depends where in Alder Valley land you were.
Apologies if I'm stating the obvious, but Alder Valley was a merger between Thames Valley (former British Transport Commission company centred on Reading, with depots including Newbury, High Wycombe, Maidenhead, Bracknell) and Aldershot and District (former British Electric Traction company centred on Aldershot, other depots included Guildford and Woking.)
TV as a nationalised company mostly bought Bristol / Eastern Coach Works products, and they had Lodekkas of various varieties, including a proportion bought second hand from other BTC companies. Example (not my Flickr account or photo)
here. A+D standardised on the Dennis Loline as their double decker - example (also not my Flickr account or photo)
here. Both had earlier, rear entrance versions, although I'm not sure how many of either survived long enough to pass to Alder Valley.
Alder Valley inherited a shortage of serviceable vehicles and maintenance staff from Thames Valley and the new company had a phase in the 1970s of hiring in a wide variety of buses from several operators to keep the Reading depot (in particular) going. A few Dennis Lolines moved north to Reading, I'm not aware of any Lodekkas that moved south to the former A + D depots, but I can't be sure that it didn't happen.
