Bluebolt If you notice the date on that Cadet is within the GUAR EXP DATE's of the machinist's vises however the Cadet only had a 2 Yr. Guarantee. That's why the date is actual.
Oh I noticed the date alright. It is the first Bullet or Cadet vise with a 1957 stamping I have found period. It is also the earliest Schiller Park Cadet. The earlier Cadets WERE stamped with GUAR EXP. The Cadets with blue dates below are stamped GUAR EXP.
