Featherweight 221J (Tan) Serial Numbers
The tan coloured 221J Featherweight sewing machines were made mostly in the St. John’s, factory in Canada, although some were largely made in the Kilbowie plant in Scotland, and then shipped to Canada for finally finishing.
A detailed list of 221J serial numbers is not available but the Canadian built 221J machines seem to fall within the range JE150000 to JE162000 from 1961. 221J machines made in Kilbowie were given serial numbers allocated to 221K's and fall within the ES873744 to ES883753 series from 1961/62.
If anyone has more detailed knowledge about the manufacture of 221J Featherweight machines, or can extend the serial number ranges, then please let us know so that we can publish it for everyone's benefit.
