Hello PJ, I suppose you've looked on the DLS ?? Type in on your search for the words Austin or Vauxhall or another make of car from that period. If not, have a look at the routes for the period from Angelah, trackplate, Lord Claude Hamilton, etc, etc, and click on the download page and then scroll through all the dependancies for that route and see what cars or lorries or buses pop up, take a note of the KUID number and if you are not happy with those particular items on that layout you can do a search under the creator's KUID number. It's a bit of research and trial and error, but I'm sure you'll find something.
