notsureif lemme say i consider myself a vintage machine hobbyist rather than a vintage machine enthusiast. so i am not one who collects, resales, tinkers, repairs, dismantles, refurbishes, restores or resuscitates these vintage beauties, i just like to sew with them. i would have no room for something as big as the 31. but one of these days i surely would like to play with one. i bet it is amazing.
