Just leave it in a prominent place on the reloading bench to make things look more impressive

take it apart so we can see the components and maybe we can work that out.

If the gauge rests on the tip of the round then I would assume you push a known round into the gauge and set zero, then check loaded rounds to be the same length.  Can't say I'd ever measure that way as ogive is far more consistent.  Is there a 'cup' type of affair under the measuring plunger?  A bit like a bullet seating spindle out of a die?  That would be useful as a precise length measurer doohickey.

If you don't want it I'll take it off your hands 😉😁

Is it not for measuring shoulder set back/headspace? fired case in, zero, resize, sized case in shows 2 thou bump etc? though not entirely sure how the dial indicator would interface wit he shoulder inside that.

Take it apart and show bits!

I agree with the last two. I bet it was cut with the reamer used to chamber the barrel and it’s gotta be either;

1. Loaded length gauge, indexing off the OGive

or

2. Case gauge to measure headspace against the reamer used to cut the chamber

Definitely something to gently pull apart and see what’s inside. Does the previous owner know what it’s for?

1. Loaded length gauge, indexing off the Ogive good call

I have looked inside it has the seating ogive that moves the dial rod so it is a bullet seating measure!.

I will post photos here shortly of the internals

thanks for the help but as said it will look good on my shelf gathering dust again

make an offer if it's of any use to you?
