Tire Changer Mount/Demount Bars (Matched Pair)

The items appear to be a matched pair of tire changer mount/demount bars, likely made of cast aluminum or a similar lightweight but strong alloy. Each bar features a distinct curved 'duck head' or 'spoon' end designed for lifting and manipulating tire beads, and a straight shaft with several integrated protrusions or 'fingers' along its length. These protrusions are offset from the main shaft and appear to be cast as part of the bar's overall construction, probably serving as fulcrum points or to engage with specific features on a tire changer machine or wheel. The overall color is a dull, weathered metallic gray, consistent with unpainted or heavily oxidized cast metal. Both bars exhibit significant signs of wear and use, including scuffs, scratches, and a buildup of dirt and grime, particularly in the crevices and textured areas. There is some visible material loss or chipping on the 'spoon' end of the right-hand bar and noticeable pitting, indicating exposure to the elements or corrosive substances. Textual markings are visible on the flat side of each shaft; the left bar clearly shows 'LB-19-R', while the right bar has 'LB-19-L', suggesting they are designed as a left and right component of a set. These markings also likely indicate a model number or part identification from the manufacturer. Given their function and material, they are designed for heavy-duty, repetitive use in a professional setting like an automotive repair shop. The sturdy, no-frills construction points to a utility-focused design rather than aesthetic appeal. The items do not appear to have any visible repairs, but their condition suggests they are well-used and have acquired a working patina. Based on the style and discernible wear, these tools are likely from the mid-to-late 20th century or early 21st century, consistent with standard tire changing equipment.
