Highways of the Empire

This would be a great find, if it could be found! In a report of the ETC's Ordinary General Meeting for June 1925, the chairman John Denison-Pender referred to a promotional film that the company that had been shown on its stand at the British Empire Exhibition, the year before. Called "Highways of the Empire", it shows "cable manufacture, cable laying and repairing, and transmission".

I've checked on the BFI catalogue and it's not there so maybe it's at PTM?
