I found my first Elna at a thrift store. It runs, but doesn't yet sew. The hook and bobbin aren't moving, though they don't appear frozen. So something isn't connected.
This is one of those borderline machines where I suspect I might be purchasing trouble. Unless I'm a complete bonehead and don't understand the ins and outs of Elna-ese (I don't have a manual), this may be hard to fix. Other than that, it's obviously a quality machine -- all-metal except for one part I found underneath the lid (a gear whose function I haven't yet figured out, as I've owned the machine all of 2 hours).
It looks OK for a thrift store machine that was sitting on a shelf w/out the protection of a case. Included was a box with cams, some thread and bobbins (no feet, though), a small screwdriver that is bent to the point of useless, and I assume this box slides under the free arm. The pedal was also included, thankfully.
Upon powering it up, the light worked and the machine ran slowly. It gradually picked up speed and the needle bar moves smoothly, quietly, and quickly. I've seen these machines in pictures, blogs, etc. and have never been attracted to the design, probably because it looked like a simple zig-zag machine. However, this particular model has a cam stack for several built-in stitches and takes cams for extra decorative sewing. The bobbin area is accessed via the back of the arm, oddly.
Hopefully I can get this thing sewing.
