Bentrel Timing Gage Kit with Dial Indicator and Adapters

This item is a Bentel Timing Gage Kit, featuring a dial indicator and various threaded adapters, likely for use in setting or checking the engine timing of internal combustion engines. The kit is presented in a dark, seemingly metal or sturdy cardboard box with a light blue foam insert, designed to cradle and protect the components. The core of the kit is a circular dial indicator with a silver-colored face, bearing the brand name 'Bentrel' (though the OCR suggests 'Pentrel', 'Bentrel' is a known manufacturer in this field) and marked with numerical increments from 0 to 100, including smaller sub-increments, indicating precision measurement capabilities. A blue needle on the dial currently points to approximately 16 or 17, and a smaller internal dial is also visible. Connected to the dial indicator is a thin, straight probe. Accompanying the dial indicator are several dark-colored, possibly steel, threaded adapters of varying sizes and configurations, including at least one L-shaped adapter. These adapters are crucial for connecting the dial indicator to spark plug holes or other engine ports to measure piston position. The components show some signs of use and age, with minor scuffs and a slight loss of luster on the metal parts, consistent with a used but generally well-maintained tool. No significant damage like heavy corrosion, dents, or breaks are visible, suggesting it's in working condition. The presence of an accompanying yellow paper booklet, titled 'TIMING GAGE PARTS IDENTIFICATION', further clarifies its purpose and provides part numbers and sizes for the adapters (e.g., F4221 18mm, F4210, F4220 14mm, F4225 12mm), indicating a systematic and complete set. The overall presentation suggests a professional-grade automotive diagnostic tool from a reputable manufacturer, likely from the mid to late 20th century given the style of the case and instruction manual.
