### ⚠️ Condition Report (Please Read Carefully):
* **Handle Crack:** Please note that there is a visible historic crack running through the black composite pistol grip handle (clearly highlighted in the photos). This is a cosmetic flaw; the handle is structurally intact, tight, and the jaw mechanism still operates completely normally and reliably under full spring tension.
* **Full Working Order:** The internal heavy-duty spring mechanisms are perfectly calibrated, providing smooth, consistent jaw pressure.
* **Perfect Calibration:** The indicator needle moves seamlessly across the gauge and returns smoothly to rest precisely on the "0" mark when closed.
* **Cosmetic Condition:** Aside from the handle anomaly, the unit is in excellent vintage shape. The dial glass is entirely clear, free from cracks or deep scratches. The metal body shows a beautifully preserved finish with minor signs of historic handling.
* **Original Wooden Box Included:** Comes housed in its original, structurally sound wooden storage box complete with its secure metal latch and clean, deep blue velvet-lined fitted interior.
