The bed of a 99K is a couple of inches shorter, and getting on for half and inch less front -to-back. The bed of a 66K is just over 14.5 inches long. A 99K doesn’t, and that’s why if you ever see a treadle 99, it’s a DIY job. Or to put it another way, the 66K is the full-size machine, and as such it fits into any vintage Singer domestic treadle base. See also my posts on converting the 99k to a hand crank and my post on restoring a second 99k.ĭisclosure: This post contains affiliate links, which means I may receive a percentage if you make a purchase using these links.The Singer 99K is the baby sister of the Singer 66K.

I'll try to explain all terms and processes thoroughly, and I'm including links to all of the resources I used along the way. As a beginner, I knew nothing going into this, and I made lots of mistakes, so I should be able to explain this to someone else who is at the novice level, too. This was my first vintage sewing machine, so I'll walk you through the process of cleaning, restoring, and troubleshooting. You can also still find parts for these machines fairly easily. This one uses a class 66 bobbin and a normal 15x1 needle. The nice thing about vintage Singer sewing machines is that they almost always use bobbins and needles that are still in production today. It's made of cast iron, though, so it's still fairly heavy compared to most modern machines. The Singer 99 was meant to be a smaller, more portable version of the classic Singer 66. The 'k' just denotes that it was made in Scotland, and otherwise it's the same as other Singer 99s, which were made from 1911 to the 1960s.

A few months ago, I found this lovely Singer 99k.

What year is my singer 99k
