Vintage Wilton Pow-R-Arm No. 301 work positioner — the big mechanical model, made in USA (base casting marked "POWRARM 301").
This is the ball-joint swivel base only (no vise included). The 301 is the heavy-duty one: machined cast iron body with steel parts, rated for 70 lbs workholding. Bolt it to the bench, mount your vise or fixture on top, and swing the work to any angle — then dead-lock it with the horizontal handle. Fast on/off action, built for production-line use.
Condition: Good, used vintage. Everything works as it should — the ball moves freely and locks tight. Paint shows honest wear and there's light surface rust on the handle shaft (see photos). No cracks, no repairs. Includes a steel shop-made mounting bracket bolted on top (see photos) — handy, but not original Wilton hardware.
