The batch of 50 O/400s numbered D8301 - D8350 was originally ordered from the British Caudron company, but the serial numbers were subsequently allotted to Handley Page Ltd, who assembled the aircraft from parts made by British Caudron and Harris Lebus. D8311 was completed in late August 1918, and was sent to France for use by the Independent Force, RAF; it arrived there on September 27, and moved to No 3 Aircraft Depot on September 29.

A Handley Page V/1500 climbs away after take-off. No doubt the seeming absence of the outermost starboard interplane struts is attributable to some photographic illusion.

This V/1500 was of the batch F7134 - F7143, built by Handley Page Ltd. Only nine of the ten were delivered, between November 1918 and March 1919. Unfortunately, the identity of this V/1500 cannot be accurately determined.
