Have just spoken to our very good cousin in Truro (NRT) and have given her the reference you require.
She does know Maxwell Adams as he was a regular at the CRO for quite some time but she has not seen him for a while.
Nancy has suggested you try contacting Maxwell for the information but, in the meantime and as she has time and opportunity, she will try and at least get an abstract of the document for you.
She has quite a bit on her plate at the moment but will do the best she can.
I did try to get hold of Max sometime back to see if he would like to join this forum, but did not hear back from him.
If Nancy can get me hard copies of the document, I will gladly pay her costs. I doubt if there is much of genealogical value in the document, but from a historical perspective it would be great to read about the purchase of The Abbey; this would have been as a result of Hen VIII's dissolution of the monestaries.
