MPN11, the link concentrated on Changi as that is filed as one of my Pinterests. If you entered yours as Tengah I'm sure you would be obliged. Tengah was of course a far off place of which we then knew little. It was rumoured they had some new fangled gubbings there called 'air conditioning'. The only RAF air conditioned rooms I ever slept in were the ASC transit ones at HKG, that is if we beat the Brit there.
ea, it would seem that Marseilles tiles were much sought after then, if only on a "Never mind the quality feel the width!" basis, from what you say. The fact that Changi Hospital and sundry bungalows were so roofed was one of those minor facts (in this case gleaned from Sqn Ldr (then) Probert's History of Changi) that stick in the mind, whereas where I've just left my car keys doesn't!
