One of the challenges with older machines is that the only option is a off label foot because the machine manufacturer never made that foot nor will they now. I have a Viking that I bought new in 1977 and at the time it was the top of the line of their machines. I love the machine but I'm at the point where I can no longer get parts for it (like the foot pedal that is now running hot) and some of the more common feet that are available now just weren't that long ago.
Even though it has scads of decorative stitches (all on cams by the way) it doesn't have some of the more common ones like blanket stitch that you find on even the inexpensive machines today. I've compensated by using an overcast stitch that looks like a backward blanket stitch. I just have to put my fabric in the opposite way!
I've seen my machine in "vintage" displays at quilt shops. To me it's hardly vintage but it's all in the eye of the beholder.
