Hi Nelson,
There were indeed no Spitires on DM.01, but Hurricanes. The translation of my dad's memoires is quite literal so I didn't change that. But I will add a comment there.
Sometimes your looking for answers for years and sometimes things come together in a day. I just got a mail from Convoyweb.org. They do have some information about independent sailing ships as well and could solve the big Singapore Oosthaven question: She sailed on Januari 30 and arrived at Oosthaven at Februari 1. So this fits most of your analyses as well. It leaves Abbekerk in Singapore not even three weeks, but I guess even that is a very long wait on a ammunition ship waiting to be unloaded while Singapore was being bombed almost daily.
That picture was taken when Abbekerk was in Fremantle, probably just hours or days after she arrived from Tjilatjap. I think you can even see the makeshift latrines and rafts. But at that time she was armed only with the 4" gun although I think I see something that could be aa gun platforms of some sort. And if the picture was taken a month later (which i doubt) she was back in Fremantle and was fitted with Oerlikons.
Drop me a mail and I can send you the picture.
Peter
