Last week I reviewed the popular Singer 221. While the demand for 221 Featherweights is high, they are by no means rare, after all, these black beauties were in production for over 40 years! Throughout it's production lifetime, Singer manufactured over 2 million 221s. Just do a quick search on eBay or Craigslist and you'll find no shortage of them. Today I'll be discussing the Singer 222k, a far less common free-arm variant.
