One man who would have been at Seletar when the OP's father was there was Mr Wee (and he was a small chap) one of the Officers' Mess stewards. Apparently when the mess was reopened after WW2, during which it had been commandeered by the Japanese, they assumed that all of the mess silver had been stolen and would have to be replaced from scratch.
Along comes Mr Wee with a couple of sacks - he had taken the silver away before the Japanese arrived and buried it! I think that guaranteed him a job for life, as he was still there in 1967, dispensing the gin and tonics with a perpetual smile!
