I bought this Singer yesterday and have had problems finding information about it. The Singer site just says 1954. The serial # is JD371539. There is a sticker underneath that indicates it was made in Canada, and I have confirmed that the 191J's were Canadian. It is very heavy, cast iron, came with what I think is the zigzag attachment and a few inserts to make different patterns. I do have the original manual. The cover for the electric cord, where it plugs into the machine, is broken but other than that it looks pretty good. I'm not sure whether this is an original case - doesn't look like it to me. I haven't done any cleanup yet. Anybody have any information on the 191's?
