This page is ordered by age, and only includes machines powered by a hand crank. A separate pictorial index includes all the machines I've ever owned.
Hand cranks and treadles were the earliest means of powering sewing machines. While treadles seem to have been favored in North America, hand cranks are more common in Europe and the British Isles. They can be a little tricky to use, but it gets easier with practice. They also stop instantly, unlike an electric, or even a treadle, which helps!

The main blog page is kept in the order the machines joined my collection (and also has other sewing machine related entries).
