My Dad left me these tools but did not tell me what it was or what is used for I have been trying to find out for years, any ideas.
Hope the pics are better, conical shape.
An interesting piece. | ||

Only one picture shows the calibrations and it doesn't enlarge. Based on that one picture I would say you have what are commonly called, go-no go measuring plugs for measuring the inside diameter of a tube or pipe etc. They were quite common a few years ago, today a laser does it faster and more accurately.
Do the 3 pcs fasten together somehow, or are they 3 distinct things? I too would like to see a closer pic/get more description of the scale markings (or any other) on it/them. It is also difficult to guess exactly *how big* they are by your pics, that info would certainly help too.
Thank you for your comments fhrjr2 and AnythingObscure, I will try to get better pics and measurements.
@ AnythingObscure, the pieces don't fasten together.
Thanks for the further pics chulirica1! Gotta agree w/ fhrjr2, they're 'taper gauges' to measure *something*, anyway...? :-) The wonderful wooden case they're in would also suggest to me that they were used by a machinist, simply because machinists tend to use lots of similarly beautifully made metal doodads kept in boxes like that...?? :-) :-) :-)
@ AnythingObscure, thank you very much for the information.
