If you have a 221,222K and need a new FC & Lead unfortunately there is nothing available. the socket set will allow you to solder the newer fitting in place on your machine and get a new fc and lead. Some work may be required to fix the socket in place. but you will be able to get a great machine running on new parts for another 50 years.
