Neat. I think that's the first straight stitch Elna that I've seen unless the Grasshopper is straight stitch too. At first glance I thought it was a Supermatic but I do see some differences on a closer look.
Come to think of it I haven't seen any truly old Elnas. Did they only start in the 1950s?
I love the variety the sewing machine world offers. So many different designs and ways to do the same thing. It's what keeps me interested.
