The top one is a 1940 Model Chevrolet civilian pattern truck, note the chrome grille and the wider top strip in 1940 cf. 1939.

The bottom truck is ..yes of course it's an Opel! Those hubcaps give it away..I knew I had seen these before, and they have 'OPEL' on them. It's possibly an Opel P4 Lieferwagen, Model 396 I think if it's a 1935-on Model. Ahem! Adam Opel AG exported worldwide under orders from the Commissar for the Five Year Plant, i.e. Goering, from 1935. Rhd Opels were exported everywhere including the UK, and this would have been a Lieferwagen imported as a chassis-cab by General Motors Java..see above. My figures show that Opel exported 10,676 Opels to the NEI and Indonesia from 1912 to 1962.

In the area of course the Phillipines drove on the left, as did Hong Kong, Malay States, Burma, Singapore, [Thailand?], Papua - New Guinea, Australia, NZ, Brunei, and I think Shanghai [and China?].
