I have used the Nova Lube(Thanks again for the info Joe) Being a vintage newbie myself- It does seem to run smoother and quieter, I am pleased.
Love my vintage,(1951, 15-91) love that I will have it for the rest of my life. The more I use it the better I love it!
So-- Congrats on your new/old Heirloom!
PS: my grandmother was a Hand quilter, boy do I wish I had inherited her quilting frames!!
