Hi Janey,
Nice work getting the needle out. Originally your Weed would have used original Weed needles. Singer never made Weed needles but the closest translation or recommendation would be Singer system 1x3 or 1x4. Weed and 1x3 needles are extremely difficult to find while 1x4 are readily available as Boye #8. The specs on the 1x4 taken from Kevin Pinkertons chart is 1.4mm round shank, 39.3mm shank to top of eye, and 45.4mm length. Worth comparing to the original. I don't believe the original Weed needles had a notched top as do the 1x4's. Here's the link to Kevin's chart which is invaluable.
