Nutloose,
I appreciate your help and input.
To be honest we have tried all the maintenance organisation where the a/c has been maintained since day one as we now have a full map of owners and maintenance organsations but so far no one can find anything.
Our only chance at present is a previous owner that we are still trying to reach and also we have learnt in the past few days that a owner quite a few years ago now had a huge dispute with the pilot. now in the end things got messy and as a result the a/c was sold on. Now we are hoping that that pilot in question may still have the logs.
We are starting to run out of places to go now grrr this is driving us mad.
