That one is definitely vintage! I'm guessing 1960s for the age and toward the last part of when the dashboard style machines were being made. Construction methods changed a lot during the 80s.
I know for me vintage is more about the construction of the machine than about exactly which year it was made. To me vintage machines are all or mostly metal with mostly cast or good quality stamped steel parts inside as opposed to the plastic clamshell bodied machines with flimsy inner workings that are being produced today. Vintage machines also have very limited or no electronics as compared to modern computerized machines.
I don't know how I'm going to feel when the modern plastic wonders start being considered "vintage". The quality (except on high end models) just isn't there. They were built to break and be tossed as soon as the finish is scratched up and the stickers fade or when the warrantee expires. Slick plastic surfaces show every little scuff and can look pretty beat up pretty quickly. Vintage machines were built to last a lifetime or longer. There are Civil War era machines that still look good and are still capable of sewing.
