Hi soonguy
I have had a look at my copy of 'British Aviation-The Pioneer Years' by Harald Penrose and was very surprised to find that Mr Melly doesn't get a mention anywhere in this book.
Next attempt was Dallas-Bretts History of British Aviation where Melly is mentioned in four entries but none that are relevant to your question. He flew from two locations (Freshfields and Waterloo) near Liverpool.
I can only suggest that you try to get your hands on a publication about early aviation in the northwest (if you haven't already) or maybe local historians in Liverpool.
Sorry l can't be more help, Mr M was a genuine pioneer and deserves to be better known.
