I am afraid that we do not have these details to hand. They may be amongst Dad's paperwork, but not easily accessible. Anyone who is interested, please provide an email address and I will forward detailed images and video of the last engine run. In terms of value, as stated, this is more about finding a good (flying) home for Dad's aircraft. That said, we have no idea of its worth. I encourage you to do your own research, refer to the details, then make a judgement as to what you consider a fair price for both parties.
Thanks for the reply.
