Leaving Rowan I met 20103 on the Saddlebow roundabout at 11.16 on what I assumed was L13 10.59 to Peterborough.
Going back to Rowan Road later, I met 20131 on Saddlebow Roundabout at 12.55 arriving with what I thought was L12 and going like a train. 20118 had departed Rowan so I retraced my steps to meet 37576 on the Saddlebow Roundabout at 12.58 with the real L12. Which means 20131 was J11, a touch late!
If 20120 really has a broken crankcase, which would explain the continual overheating, it is a new engine job. and there was no sign of the man preparing the B12s for departure for the third week running so no progress on 20506"
