Hi all,
Thank you for your lovely replies, and taking the time to help!
I'll try and get the photos smaller and see if I can upload them! Shame it didn't work the first time, I'm not the best with these things 😅
Thank you for the link to the keys, I'll give that a look and might be able to get one that fits; the hole looks square so that seems like a good starting point
I do have one of the "bullet" bobbins, I have the same type in my hand crank too, so I think I have a theme going now!
I have just managed to get it to see and it works wonderfully so I'm very pleased about that!
