Great info there Nigel,
I must admit I had forgotten what registerations the VEX--X's were going to have, had they not been transferred to ECOC. Just going through my pics, I have found the id of the LHS used on the Cambridgeshire Pick Me Up Routes, it was LHS936, registered WNG105H
Later in their Cambus years, when the company were going through a period of allocating specific vehicles to outstations ( I think this was the mid to late 90's), St.Ives outstation got allocated with less than 295,296 ,303 & 304 + two others, which meant it got rather boring VR wise from a enthusiast perspective. , especially if one of the others also happened to be a VEX---X vehicle ! The 6th one allocated initially was OPW180P, howeever as time moved on, it was changed to YWY830S, for once not a native vehicle !
I wonder if anyone did find anything else out re VEX298X, would be nice to know, as its no longer listed with the preservation group I thought it was, according to the Buses Restored 2008 book.
