PSLE Examination Papers (2017-2019) with answer keys published by EPH

I don't have those books on hand but a few of us in my mum group have been looking out for old EPH papers too, so you are definitely not alone in this search. You could try posting in the Buy and Sell Singapore Facebook groups or Carousell, because I have seen these pop up there every now and then when parents clear after their kids finish PSLE.
