My friend gave me a portable handcrank that someone gave her 20 years ago in England. She has just had it in storage. I was telling her about my treadle and she said she had an old machine she thought I would like, so she gave it to me! It is a SERATA serial #640765. I have been searching and haven't found anything yet. It has a beautiful wooden case with inlays. Not sure where to find info to date it or get parts. {she went to show me the extras inside the sliding wooden drawer and found that the bottom was missing. she has no idea which move it may have been lost in} I will download my pictures later tonight and post them soon.
