B & C reg Northern ECW Leyland Olympians - Cummins L10 & Voith

P reg Northumbria & Arriva Volvo Olympians - Volvo D10A-245 & ZF**

S reg Coastline/GNE Volvo Olympians - Volvo D10A-245 & ZF

** Although the P reg examples were predominantly used in North Tyneside & Newcastle, I did have a sweet spot for the Cummins L10 & ZF powered ex London & Country and original 602 Palatines when they both did spells at Blyth on the 308. The Pennine livery wad striking on 372/7372. Although I've come across photos of it when at Hexham, have never come across any of it when at Blyth.
