Case length is one thing, headspace is another. Do you mean an appropriate tool for measuring the distance from the face of the case head to the shoulder datum line? If so, it looks like the Hornady E bushing, .420" #E420 for their comparator is what you want.
Redding makes a form and trim die, Lee makes a quick trim die and most all of the majors have.366 trim pilots for their case trimmers. I don’t know if Lee makes an 9.3x62 specific case length gauge for their trimmer. And, as mentioned above, the Hornady comparator set. Hornady makes two different types of comparator sets for different purposes: a bullet comparator and a headspace comparator.
All the usual suspects make 'em. Some call them this, some call them that. They do the same thing.
At one end indicates case length min and max tolerances, the other end indicates any possible shoulder issues with case head min/max tolerances. Just drop the cartridge case into the gauge and get a two-fer.
LE Wilson just calls it a case gauge. I was hoping they'd make me one since they're just down the road a bit, but no luck.
I've a call into Hornady's custom shop. We'll see.

It's you and the bullet, and all the rest is secondary.
Would it really be too much trouble to measure the headspace dimension with the off the shelf Hornady piece and the length of the case with calipers? You would then not only know if these were within overall tolerance, but also what they are.
