Each tool has a number but no name they snap into the metal box in the photo any info would be great thanks

I'm surprised that nobody else has come up with a purpose for these tools yet, which I myself can't help with either, but they look really cool and more importantly really *specialized* for whatever task they are meant for. Seems logical that they could be things for an auto (tractor, etc) engine mechanic to use (valve tools, or brake tools, or whatever) but if that was the case somebody would have clued us all by now, which leaves me guessing they're for some other not-so-common 'calibration' process of something for either building or fixing machinery.
Hope we all get an answer to your questions, so we can all learn what they really are?!! :-) :-) :-)
Thanks for chiming in hope someone knows what they are for
These look like "go/no go" gauges to measure tolerances of maybe small shafts. Smaller than one "bump " but larger than the other. Can you use an inside micrometer on the bumps? Doe the numbers represent thousands of an inch."
I want to say Music tuning forks, used to find pure tones from resonation and yet could be forks for electrical work/application.

I agree with everything Motoolz says in post#3. TO ME, This "LOOKS LIKE" the kind of specialty measuring tool used in production lines by Machinist and Inspectors, or others.
PS: Now that i have said all that, it will surely turn out to be a left handed tuning fork. for a right handed piano !! LOL.........
Take Care,
Wayne
I do not know anything about these or what the numbers mean but thanks for chiming in someone knows out there exactly what they are?
Hey! I got someone who "almost" agrees with me! That proves I,m right! Right! Part of the fun is the different "opinions" I enjoy this site
Two of us who agree w/you Motoolz... ;-) and I also wholly agree how enjoyable this website is, for those (most?) of us that like 'learning new stuff about old stuff'...
:-) :-) :-) :-) :-)

"PS: Now that i have said all that, it will surely turn out to be a left handed tuning fork. for a right handed piano !! LOL........."
<LOL> too, my CW friend. I can't agree with Thomas's suggestion of 'tuning forks' (though it ain't impossible) because they don't usually come with the little bumps on their insides like these tools have...oh yes, I've got a few legit 'tuning forks' laying around my house too, not to mention a half a herd of really good left or right hand pianos that don't actually belong to me... <LOLOLOLOL>
I also believe that they are specialized calipers. And looking at the case closer, it appears that they are protected in there.
I did out of curiosity look into tuning forks frequency for ENT doctors and radar gun calibration. There was some military device that used similar frequency to the marks, but the forks looked different and these appear to have handles. That would point back to a hand held measuring device
One more observation -- the numbers stamped on these don't strike me as common ''tuning fork' pitch numbers, the most common of which would be something like "A-440" which would be the first (if not only) actual tuning fork a piano (or organ) tuner would start with. Still hoping we all somehow discover what they really are, though?!
:-) :-) :-)
Just a couple of questions. The two that are marked 147-153. Seem to have a post on the end of the flat handles. The post seem to have a step or groove. Do they have two different diameters? Have you "measured"" one tool with the other ? Do they "fit" between the bumps? Do you have access to micrometer to measure the post in relation to 147 and 153. I'm still thinking go-no go gauges until you decide that can not be it.
So I was thinking the other side was a handle that interchanged...but..what if we're looking at it backwards? It appears the flat end with notch are the same size? What if that end clips into a...solder or heat gun...and the round end was the business end?
The ones woth the round pieces..not sure? Maybe extentions or special use?
The 147-53 do have a step and a groove in the post on the rear they appear to be identical
The forked ends of the rods perfectly snap in to place on the rod in the box therefore I believe the cylindrical ends are the gauges or? and the forked ends are the handles
After looking at them more closely from smallest to largest the sizes are as follows
.130,.135,.140,.145,.150,.280,.320 and the two marked 147-153 with the step and groove
Ok..does that forked end with notch fit the black ones where the round part is? Kinda like an extension piece?
The box was interesting..that little box part in the upper left..like a handle or something went there.
No the forked ones do not fit the black
My 2c worth: They look like go-no go gauges. Possibly for sheet metal?
A further suggestion: Go -no/go or wear gauges for roller chains?
One end would measure the wear on the pin/roller and the other end would measure the stretch of the chain.
