✅ SOLVED Test your skills on this one! Spent years trying to ID this.

[musclecar]

I found this in Alaska about 10 years ago, and have never been able to ID it. It is an aluminum piece, about 3 inches square. It has 15 teeth and is numbered 1-15. There is a stop preventing it from spinning freely. The back has two tabs that may have been used to mount it. ANY GUESSES?

Thanks,

MC

PS The quarter used for size was found yesterday! 1935S Yeah!

Is there such a thing as a 15 Minute Egg ?

Yes. Used as an artillery projectile!

Perhaps this is the way to look at it? Not any closer to an anwser but any way something to think about.

Thanks all for your input, but I am still not quite convinced. If I dig way back into my hard drive, I kinda remember somebody saying something about an airplane part. Maybe something to do with altitude. I forgot, cause I couldn't perceive what he was talking about. Maybe that will help.

Or...

 

[mercinarie]

if they mounted it that way wouldnt they make the numbers so they are the right way up when they go past the pointer thingy.

 

[dg39]

Although I do think Montana's idea might work.

I have seen something similiar mounted on either a fence ,or a rabbit cage I don,t exactly Remember,but could it be used to keep track of some interval like vaccinations or innoculation?

Haven;t got a clue as to what it was used for, but the the theory of being mounted on a fence sounds good..the bottom tabs would slip in behind the wire and then the tabs on the back would slip over the wire and then be bent closed ..both holding whatever it is in place. Maybe DNS uses it to count the illegals coming over or under the fence...

Where are all the aeronautical engineers and pilots? They certainly would know if it were an airplane part. If they don't know what it is I would bet it's NOT an airplane part.

I dunno... seems kinda light-weight to be a reliable aircraft part with no real connections, and a dial for what? I'm no expert (nor a pilot) but have several hundred hours in N-Model hueys... and even those late 60's bare-bones choppers didn't have dials that were static or light-weight like that.

Now my guess is that unless one of the boys that builds them comes in here with a different story Montana Jim can be relied on that this is not an airplane part. He seems to know a little bit about aircraft, and when you've had flight time (although not a pilot), you can't just "know a little" about what your talking about.

I hope I learned something after 23 years in the Air Force! I'd sure like to know what this thing is though, and that damned acorn with spikes!

Isn't the spiked acorn thing settled? I thought it turned out to be an anti-theft device for a watch.

so how does it protect your watch from being stolen

What about a parachute timer? Isn't 15,000 feet the usual limit on height except for HALO (High Altitude Low Opening) maneuvers?

perhaps, now this sounds a bit odd, a fish counter clipped to the side of a boat or fish basket, every fish one click until you have reached a limit of 15?
