singer 413 problem?

to be honest i think i have the wrong bobbins. the correct ones look to be domed? mine are not. timing seems to be right judging by the timing marks on the needle bar and the fact that the needle and hook meet at the right place.

you have what is known as an apollo bobbin case. black on later models grey on the older models, between the edge of the bobbin case and the silver bar there should be enough gap the thickness of thread, you can adjust the closeness by the screws on the right, if that does not work you will need to retime it, I can send you timing instructions but this site does not allow email addresses to be shown so type my email address as you say it not as you see it.
