BTW - my manual is "Vertical Feed Sewing Machine" I've also seen teh "Davis Vertical Feed" manual, and other than the Introduction and a very few places that show the Name, they are the exact same manual - down to the page numbers and pictures.
I've also got a download of the earlier VF machines, but I really wanted one to go with my machine. They don't come up on eBay very often (then then two came up at the same time LOL!!)
