Hi again dear vintage sewing machine experts,

Thanks to your recent tips and advice, I’m progressively retrieving online the missing parts I need to restore my White Electric Rotary Model 43!

But I’m still having a hard time trying to find a particular type of bobbin case (see the attached photos). So far I’ve seen a lot of "wishbone" bobbin cases from the same company, but not the specific type my machine seems to require, at least according to the user manual (see the image)...

Do you know where I could find these? Or if another/more recent type of bobbin case could fit my machine as a replacement option?

Thanks again for your help!
