Kees has it right, and the reason I selected the Burgess “Gunbus”. A number of these machines were acquired by the RNAS, but proved unsuitable. Based on Owen Thetford’s BRITISH NAVAL AIRCRAFT SINCE 1912, 36 Gunbuses were purchased and given serial numbers 3657 – 3681 and 8258 – 8268, a small difference with the source used by Kees.
