I bought these in a lot for the micrometers and and small thread gages. I am selling approximately 70 of the snap type gauges and thread proving gauges. English made, high quality and a few are still new. Horstmann Gear, Yorkshire Precision Gauge (YPG), Matrix and Southern Gage Company. Type C, U and A; flat, knife and cylinder pins in sizes from 1/4" to 6 5/8". Thread go-no go gauges are OD and left and right in the following sizes: 3/4-16, 1-12, 1-14, 1 1/8-12, 1 1/4-12, 1 3/8-12 and 2-12 in 2A or 3A class. I will sell these separately for $5-$35 each for the snap gauges and $30 each for the 2A and $40 for the 3A thread gauges. A few of the snap gauges have been checked on a certified CMM and are within parallelism limits. ***If you are using the ap: "Call" for quickest response, if you press the "Chat" button it goes to email which can take up to 24 hours to reply to.
