This is a high-quality precision caliper in excellent condition with significant historical value as well. This item was used in Project Gemini at the Martin Marietta plant in Baltimore, Maryland in the 1960's. This is evidenced by the printing in white lettering on the end of the wooden storage case, the metal tag and yellow calibration sticker on the storage case, and the repair tag included in the case.
