Hmmm, my earlier response seems to have been lost

Harold Oswald Day Wilkins PoW 28.7.17 in Martinsyde A3986

John Leo Whitty DoW as PoW 8.7.16 Sopwith Strutter A384

William Hedley Winter PoW 11.10.17 Camel B6314

Horsley presumably Clement Flegg Horsley but can’t see his being taken PoW

There was an ET or ETL Jones with 2Sq but again can’t see PoW data
