Many months ago we contacted Janome because we had customers that needed these straight stitch plates, and we were told that they had a part number, but that the number wasn’t in the ordering system yet. That being the case, we couldn’t even pre-order the plates. Last week we placed another Janome parts order, and when we checked to see if the plates were finally in the system, they were!
Since Janome is the manufacturer of Elna and Necchi sewing machines, it is possible that this straight stitch plate would fit some of the Elna or Necchi machines as well.
See it in all its glory:
