I would agree it isn't an N7 however 68642 was a J68 rather than a J69, it got around a bit which was usually the sign of a duff one so,

Col said and he was right.
The second J69 in the line up still has the GER pattern roof profile so was probably one of those sent to Scotland and later returned to Stratford.
