Well, I think some do. There is a skilled repair guy on a vintage Elna yahoo group, his wife has taken on a Supermatic and set up for quilting exlusively. A few on that group fmq on various vintage Elna models. As you well know, it has a lot to do with getting tension right and adjuting for the thread you use.
Yes, Elna 1 and 2 have similar cases, they all double as an extention table, but come in slighly different designs. I have the beige two-tone colored Supermatic, there are an all green and a two tone green Supermatic too. Again; all the Elna 2 are the same machine with just slight differences on some features (cam slot and satin stitch fine tuning knob differ a bit). My Elna has a two part case, and only one part turns into the extention table, on some the case is higned and the entire thing cleverly folds into a nice extetion table. Elna 1 should in theory be about the same as the Supermatic when it comes to free motion stitching. I don't free motion much at all, and I'm not the one who should give advice on that part.
