JIMS Universal Clamp and Barnett Clutch/Engine Component

The image displays two distinct mechanical components, likely related to automotive or motorcycle maintenance and modification, given the observable branding. The item on the left is a vibrant blue, anodized aluminum clamp, possibly a universal fork clamp or a similar mounting bracket. It features a robust, C-shaped main body with an adjustable screw mechanism for tightening. The visible fasteners appear to be steel bolts and nuts. The blue finish shows some wear, including scuffs and small chips, indicating it has been used. Engraved on its side is the brand name "JIMS" with "U.S.A." underneath, suggesting a manufacturer from the United States known for producing specialized tools or parts. The craftsmanship appears to be industrial grade, designed for strength and durability. The item on the right is a circular, dark grey or black metallic disc, resembling a clutch pressure plate or a performance engine component. It has a central hexagonal bolt or nut, which appears slightly worn or tarnished. Engraved on its surface is "Barnett" in a stylized script, followed by what looks like "International" and an unreadable location, likely the company's full name and headquarters. Below this, there's a part number: "317-30-30002". The surface of this disc also shows minor signs of use, possibly some light scratching or slight discoloration around the central bolt, but generally retains a clean, matte finish. Both items are precision-machined, indicating high-quality manufacturing and specific functional purposes within mechanical systems. Given the brands JIMS (known for Harley-Davidson tools and parts) and Barnett (known for clutches and cables, notably for motorcycles), these items are likely specialized tools or performance parts for motorcycles, possibly late 20th to early 21st century given their modern manufacturing appearance.
