I finally got the hand wheel and the face plate off and took a damp rag to the table/base. The machine is not quite as bad as it looks in the initial pictures. Most if not all the decal is there under a lot of grime. The screws in the back plate are stuck so rather than messing them up I'll let them soak over night with a bit of oil. Hopefully it will come off and I can see why its locked up. There was a bit of rust on the presser bar shaft and most of it wiped off with the oil. I am taking pictures as I go so others can see but also so I know how it goes back together should I forget something or end up with a spare part :0
