Hello,
Currently on ebay are photos of Royal Aircraft Factory H.R.E.2 No.17 in its landplane form at:
https://www.ebay.com/itm/Royal-Aircr...gAAOSwxe9ftN5x
and Royal Aircraft Factory B.E.2a No.267 at:
https://www.ebay.co.uk/itm/1914-Photo-Postcard-ARMY-AEROPLANE-B-E-TYPE-Royal-Flying-Corps/203182069131?hash=item2f4e98558b:g:w0EAAOSwwz1fmHz %20c
The latter may presumably be seen in Paul Hare's new book on the B.E.2a which includes the history and photos of all B.E.2a aircraft:
