D1015 'Western Champion' thrashes out of Westbury - Saturday 6th July, 2024

The iconic mainline Class 52 diesel locomotive, D1015 'Western Champion', is seen departing Westbury on the return leg of 'The Westbury Wizzo' running from Cranmore to East Midlands Parkway.
GBRf 66309, which accompanied the charter for the top and tail run to Cranmore, can be seen in the background, having been detached from the train at Westbury.
A video of our first trip to Westbury in over seven years will be made and uploaded by tomorrow afternoon.

I'm curious about the fourth coach (labeled D in a window): it's an air-con Mk.2 (i.e a 2D, 2E or 2F) First Open, but it also has a small buffet section, complete with a red stripe above the windows. What's up with this? No Mk.2s were built with catering, so when and by whom was this coach converted?
