Mizkaki, Is the end of the spindle a sharpening stone, or is one added on to it? My Gritzner has that spindle on it's bobbin winder, and I was wondering just why. Now I know. Do you also know why it has two spindles for thread? Caroline S kindly uploaded pictures of my Gritzner hand crank to the Vintage machine photos, so you can see it there, if you wish. Wouldn't the same needles that you recommended to me work in the Phoenix too? I have a feeling they are both of the same time period, as the top of my machine's case looks a lot like the one pictured above.
