Rare 1950s Scintilla S.A. Lesto Jigsaw Nice! Swiss Made With Wood Case Pre Bosch. Tested and working great! Power cord has been replaced. This model was the world’s first jigsaw, which was developed in Switzerland by Scintilla AG, which later became a Bosch subsidiary. I don't think this was the original run from 1946, but most likely the 1950s.
