The quirk of the engine instruments on the 734 (and some others) was that the block of main engine instruments (in 2 columns, engine 1 on the left and engine 2 on the right) was positioned just to the left of the block of secondary engine instruments (again with 2 columns, engine 1 on the left and engine 2 on the right).
The problem was that looking only at the 2 central columns, you were seeing the main instruments for engine 2 (right engine) on the left, and the secondary instruments for engine 1 (left engine) to the right. So a very odd situation of engine sides apparently being reversed IF ONLY the 2 central instrument columns were examined.
In the Kegworth case, the high vibration indication of the number 1 (left) engine was positioned just to the right of the number 2 (right) engine N2 instrument. This might well have compounded confusion, appearing to confirm a right engine problem in a pressurised, high workload moment.
Please see post NO 31 where I posted image of 737-400 EIS display. I am not sure what you guys are talking about because it seems to me that the gauges are perfectly normal with No 1 on the left and No 2 on the right. Can you be more specific ? I could be seeing things at my age!
