The 1880 was made in 1977 and it has free-arm capability, uses cams to create decorative and utility stitches, and it takes a 15X1 needle and a class 15 bobbin. (The blind hem may be built in and not need a cam)
I would accept it in a minute. :) A little cleaning up and perhaps replacement of the belt and it could sew for another 50 years.
