Indulge in bore measurement luxury!
Helios is (was) a German tool maker of some repute. imo they are excellent, the Germans would tell you every bit as good as the Swiss lol.
These five bore gauges sets cover 0.157" - 6.3". All anvils are a present, all indicators work well. Indicators are thou and tenth, 0.001" and 0.0001"
The ranges are in stated in metric but the indicators are imperial.
Helios 4-10mm dial bore gauge
Helios 10-18mm dial bore gauge
Helios 18-35mm dial bore gauge
Helios 35 - 50mm dial bore gauge
Helios 50-160 mm dial bore gauge
Full disclosure, a few indicators were sticky. I've fully service those (98% of time its just cleaning). There was a cracked jewel that I fixed and one rev counting hand needed replacement. imo they are all good, and Helios made an excellent indicator.
Just selling because I have too much stuff and these are duplicates.
