This website gives details of the Leyland Nationals delivered new to National Welsh Omnibus Services Ltd, and its predecessor companies Western Welsh, Red & White and Jones Omnibus Services Ltd, Aberbeeg.
These have not been included in this survey (principally because they were purchased in the period 1980 - 1982, by which time I had left South Wales!)
I am grateful to Richard Waters for additional details of depot allocations, which I have started to add to the vehicle data table. Richard has also created a website on Gloucestershire Buses, which includes a detailed history of Red & White. Unfortunately, this site seems to be offline at present.
As photos are a major component of this site, I have changed the width settings to pixel values to ensure a more consistent appearance. It is recommended that the site is viewed in a browser such as Safari, Firefox or Opera, as these all offer a facility to vary the size of the displayed area, despite the fixed width setting. These browsers are available as free downloads for Windows and Mac systems - just click on the names for more details.
The 2015 update includes converting the pages to use PHP instead of HTML templates, which inevitably means that the URLs have all changed. I have provided a redirect facility, so that any existing bookmarks should still work, but please let me know if you experience any difficulties in this respect. The pages have also been reconfigured to make them (where practical) suitable for viewing on mobile devices with small screens.
