The aim of this document has been to try to set out in one place the history of this notable instrument, together with an accurate record of what Cavaillé-Coll material was found to remain in the Manchester organ after its careful dismantling in late 2020. [..]

This document also lists those areas where research work is now necessary in order to formalise the design for those parts of the instrument that have been lost and are to be reconstructed. A summary of the approach to the work that lies ahead concludes the document.
