For those who want to maintain their own machine, a great help is to get the DVD "Those fantastic Featherweights" with David McCallum. Even though it is intended as everything you need to know to clean, maintain & restore a Singer 221 FW machine, you will really understand any of your old Singers. He also covers how to restore the old cases which may have developed a musty smell or replacing broken handles & latches; this DVD is 3 hours looooong & very thorough. He does talk about the 301 as well. You will find the locations for oil & grease (gears) shown in detail, and are common amongst most early Singers. Happy sewing on the oldies but goodies.
