Thanks! I have arranged with the seller that I will buy it, but I will ask him first to open the stitch plate and take a photo, for if the bobbin shuttle is not there, I will have to spend more on it than on the machine!
I have never seen a vibrating shuttle before, except just now in photos on the internet. So, is it just a shuttle, or is there a shuttle -and- a case, as with a bobbin being a bobbin plus a case?
I have to be able to ask very simple questions/give very simple directions to the seller to ask for info/photograph, as he does not know about sewing machines.
Thanks in advance,
