How to Identify Petersen DeWitt Vise-Grip?

• Look for the 'DeWitt, NE' or 'DeWitt, Nebr.' stamping on the handle or body to confirm the original manufacturing location.
• Check for the early 'Petersen Mfg. Co.' branding which distinguishes these from later mass-produced Irwin versions.
• Examine the adjustment screw and release lever design, which should reflect the robust, thick-gauge steel construction typical of the 1940s era.
• Verify the presence of the original patent numbers often stamped directly into the steel frame.
