I bought an Elna today, in the case. It has accessories with it, seller explained to me how the lever has to be pushed to run it. It is the one called the grasshopper, with the case that works as a sewing table. It looks in very good condition. That is about all I know about it. I will have to get a photo or so to post on here, but I thought it should come home with me, just because, lol. The number on the plate on the back is 500970. It has a list of patents from 1939 and 1940, and a Good Housekeeping guarantee plate.
