Janis,
Several trips ago to Indy we went through Martinsville looking around. We have a friend from another forum that lives near there. Didn't see him as he's a Dr in Indy and was at work, but did like what we saw in Martinsville.
Found an antique store and found some shuttle bobbins we bought.
The Singer lube is I think a dying product. It's the only lube for the old Singer motors and I'm sure Singer would just as soon see all those old machines die. It wouldn't surprise if sometime in the future they discontinue it. Those of us that use the stuff would be well advised to lay in a life time supply for our Singers.
Joe
