Don't order anything just yet!!!!
At the RAF Museum, DORIS holds the RAF Forms 1180 and these record accidents and some incidents - definitions change over the years. These 1180s are filed by aircraft type, in date order, well the other way round actually. I suggest you arrange to go and look at the docs or ask DORIS staff if they will do so for you.
If that does not bring an answer, next try the RAF Forms 540/541 which are held at the NA Kew and can be readily accessed by a personal visit or by getting a researcher to do the job for you - £20 an hour or thereabouts.
