Adjustable Metal Bars (Likely Alignment Tools)

The image displays two metal bars, likely a pair of specialized adjustment tools, possibly for automotive or machinery alignment. Each bar appears to be made of a sturdy, possibly heat-treated, steel or similar alloy, exhibiting a metallic gray to dark gray coloration. The top bar is a single piece of flat stock, approximately 1-2 inches in width and around 18-24 inches in length, featuring a slight taper or shaping at one end. Attached to it is a small, dark-colored knob or screw mechanism, suggesting a clamping or adjustment function. The surface shows some wear, minor scratches, and perhaps slight discoloration, consistent with use. The bottom bar is similar in overall dimensions and material, but it features a different attachment point, a cylindrical metal collar with a set screw, which appears to be a sliding or adjustable guide. One end of this bar also exhibits some shaping, possibly for engaging with a specific component. Both bars show signs of industrial use, including surface abrasions, minor nicks, and some loss of original finish, indicating a patina consistent with age and regular operation. There are no readily visible manufacturer's marks, stamps, or significant engravings that would identify a specific brand or model. The construction appears robust and functional, suggesting they are precision instruments or parts of a larger tooling system. Their design implies a purpose requiring leverage or precise displacement, typical in mechanical adjustments. Given their appearance and common applications for similar tools, they likely date from the mid to late 20th century.
