Handley Page Heyford K6902 – Radar Trials – markings information

Hello folks,

Just building a model of this machine for a RDF display in the Sywell Aviation Museum but am struggling with markings! I imagine it would have been all over NIVO as they all seemed to be – but I have no idea of any markings beyond the serial number. Also I am doubtful that it would have had armament fitted as it was loaned to the RAE for trials….any Heyford experts out there who could help?

Many thanks in advance!
