Stephen, you hit the jackpot with that auction. I have never seen one with the box and instructions. I love collecting and I'm lucky enough to own 2 of these gems. This embroidery attachment can be used on other vertical bar, low shank sewing machine models. So far I've used it on Singer models 221 and 222 Featherweights, Singer 99 and Singer15-91 I'm pretty sure you use it on other manufactures machines as well.
