Help to identify a Battle of Britain signature
 

Dear all,
I am trying to identify the names of the two Battle of Britain airmen who have signed a document I own.
The signatures are on an item dating from the 40's that was signed at a Battle of Britain reunion in 1949. There are several other BoB signatures on it that I recognise.
I'm normally pretty good at this but these have me stumped.
Grateful for any assistance you can offer.
Gerry
