Hello,
Currently on ebay are two photos of Handley Page aircraft as follows:
Handley Page O/400 USAS

Handley Page V/1500 J1936 Old Carthusian
https://www.ebay.co.uk/itm/4-ORIGINA...YAAOSwGk5f7RME
I'm not sure if the first photo has been previously seen as some of the sellers other H-P photos are defintely familiar.
Regards,
Clint
