Glenn, your time has been well spent here. There are tons of vintage machines that will be salvaged due to this thread. While most folks treasure looks over function, this method of restoration will be sure that each is worthy of best of both worlds!
Just remember folks, these machines have history worthy of saving, stitch by stitch. Each time you "fix" a machine to increase its value, even if it is just its looks, a wee bit of the past is saved. Our young ones are paying attention, to be sure!
