Hallo,
Type separate searches of Euston, Rugby, Norton Bridge, Stoke-on-Trent adding 1990s into YouTube, there are some great clips to watch. Whilst Executive 87s can be seen hauling or pushing MK3+DVT sets, all the 86s appear to be swallow, or without logo
There is the odd MK2f Set with MK3 RFM and no DVT but with a BG, and my favourites a MK3/MK2 + DVT set with a BG between the DVT and the FO and even a set with MK1 TSOs in I/C livery
hope this helps
