Upon closer and more informed inspection, this is a 9 head, not a D9. I can't share bobbins or needles. 😒
However I did stumble on an article offering a bobbin replacement since the 9 uses the 8 bobbin and they are super scarce. SKC knitting accessory tatting shuttles have a removable bobbin that is slightly smaller than the 8/9 bobbin, but fits pretty well except a bit more rattly.
And also there is a stop built into this which allows it to use standard DBx1 needles.
So I'm off to outfit my new baby with bits and pieces and dig further into mild disassembly for cleaning because something is a bit sticky feeling.
