Mike has summed up my own assumption. My RP is chassis number 166898 and has engine number M166679. I'm very fortunate in having the full set of logbooks for the car, back to its first registration on 1st February 1933, so I can be certain that it's had the same engine from day one. If the engine was indeed taken off the line for rectification, they must have done a good job; it's still in regular use with well over a quarter of a million miles behind it.
