I did a litle research, and found Sunnen precision bore gauges of various flavors (models) have calibration procedures in GIDEP (Government Industry Data Exchange Program). If your company is a GIDEP member you could get procedures for some models from GIDEP. What those are, is military calibration procedures for these. I can't send those, but if you give me a specific model, and some specific detail on what you need, I could extract from the procedures. Let me know the model number of the gauge you have, and I will take a look.
