Thanks for the comments.
I have a set of calipers from HF and they work fine. I was just learning to impression keys and found it faster to use the gauge to file to the next cut.
The folks at LAB are looking into the problem so maybe we will have an answer one day.
Some research I did seems to show that perhaps the gauge is for one of the following lock/keys;
RUSSWIN, series N Class, pre 70, 9 cuts
DEXTER all cuts are .005 higher on the gauge
LOCKWOOD
I agree, not many would ever want or need to gauge a Master K1/M1 key.
Thanks again...
Steve
