I have a 99K made in Scotland (like me).....it was a gift from my daughter
I bought the oil, grease, bobbins and an extra belt from sew classic.com. They have everything you need for just about any vintage machine.
I have two featherweights, a Singer 185K, a Brother Jean machine and an 1898 S Niger treadle.......
I should also say I have a Janome MC 6500P ... It is a great machine too but my old machines put it to shame for the thicker seams I sew!!!!!!
