In perspective, they could just end up refurbishing 6118-21 (even though it would mean 1x odd spec Coaster in corporate livery). This would then give Percy Main 4x spares to cover the 1/1A/309/310 (6100,19,20,21). 6118-21 are only 12-15 months younger than the Cobalt & Coast B9TLs in theory so it would make sense.

I believe the 6118-6121 are actually older. I may be corrected, but weren't ex-dealer stock and only registered when GNE acquired them when they bought the the streetlites in 2015; which is why they have 15 reg plates. I think they same age as Red Arrows.
