WHBM, it's much more detailed than the map you posted the link to but there is no timetable information. At the start it says:
"This folder has been specially produced as a guide and souvenir for passengers. The map included is accurate and drawn to a scale of 64 miles to one inch, and conforms in detail as far as possible to the Pilots' flying maps produced for Imperial Airways Limited by "RaynOil" Maps Limited. Mileages and magnetic courses are shewn (sic) throughout the map and the air views are of towns or places all of which are either flown over or passed near by.
It should be particularly interesting to passengers to calculate roughly the flying time from place to place, and then with the air view as reference be able to locate one's approach to a place of landing.
We particularly mention air views of towns and harbours between Singapore and Port Darwin, most of which are flown directly over.
All the air views in this folder are located on the map by the name of the town or place being framed in red."
I will gladly email some photos of the maps if you send a PM with your email address.
