As indicated in what SteveH posted, you need to figure out who the actual MFG of the machine is - and many are White. Please post a picture and hopefully we'll be able to identify that for you. Once you know the actaul MFG, then getting information and supplies is much easier.
This is my AG Mason MFG machine, made by White and takes the same bobbin, shuttle, needle and attachments as other White made VS machines.
