Build: Heavy-duty cast-iron frame with nickel-plated uprights and guide cylinders. Functionality: Allowed users to lock in specific angles (typically 45° and 90°) to guide a specialized back saw.
Accessories: Often used with specific wooden beds that were attached to the frame to support the workpiece.
