Hi,
Sort of curious whether the "1887" date was gotten through paperwork or patents on the machine. This is my mental image of your Domestic as well as owners manual:

Like Cathy says, new needles have not been made for this model in many years. Back in the day, the needles for this machine were called Domestic NT (notched top), 1x4, or Boye #8 (brand name). I don't think you'll have any trouble finding these needles. Good Luck.
