US made 66 machines from 1948 probably have the revers lever, the UK made ones doesn't turn up that often with stitch length lever. It's easy to tell the difference; it's either a stitch length turn-knob (no revers, early version), or a lever you move up or down (with backtak, later version). It's a nice machine either way though, and in very nice table I would be intersted. However, you can only use one machine at a time, and I actually only need two or three. I have five!
