Hi /diy/, what is this?

I dunno why should we help you lmao. Google it fag.

>>1510335
some vernier measuring thing?
>>
>>1510353
I thought it was something like that. But it is supposed to be nailed to the workbench and so, be used in a fixed position.
>>
Is there any kind of labeling on it at all aside from the measurement/setting numbers?
>>
Seems like it's some kind of device that may be used to scribe large curves/arcs, but if it's bench mounted that wouldn't make any sense. Maybe it's supposed to be mounted some other way, like on a wall or moveable arm or something.
>>
I saw some shit on the history Chanel years ago about how coins are made and they had a thing that look that, what they did was.

make a big ass "coin" out of clay
let it dry
and they when they use this tool to trace the big ass clay coin it moves the other end exactly 1/10 or 1/20 the side they are moving. so they can get all the details into the coin molds.

I guess its kind of like a pantograph

I could be tottally fucking wrong though.
>>
>>1510423
>thinks it’s a Reducing Machine

Wrong.
>>
>>1510425
welp I just be over here sucking dicks until somebody guesses right then
>>
where did you find it. in a shop? if so what kind of shop.

like if you found it in a dog food factory its probably got something to do with dog food.

of course if you got it from a crazy old lady at a flea market then I guess its got something to do with crazy old lady bits.
>>
>>1510332
Looks like it maybe it used to hold bellows for blowing air. Is it hinged at the one end?
>>
>>1510332
It's a faggot detector and its pointing right at you OP!
>>
>>1510439
Wouldn't make any sense for it to have all those gradations & settings just to hold a bellows and blow air.
>>
I would guess it's a machinist or fabricator's measuring device. It could be specialized for one process of one item's manufacture.
Does it move?
>>
My granny had a bench with a simmilar thing mounted. she was a sewer/dressmaker

I meant a workbench

sorta looks like a gun laying computer.

A watch press to press the back on after servicing
>>
>>1510343

Well, Google is never wrong. It's definitely an airsoft gun. So now the question becomes, how do you load /shoot it?
>>
>>1510510
Have you ever seen a watch?
>>
>>1510332
Could this be to trace a pattern, making the copy scaled bigger or smaller?
>>
Pentagraph
>>
>>1510510
That is definitely not a watch press.

Less demonic tho.
>>
>>1510736
Yes, thanks.
I guess OP doesn’t have one...
>>
>>1510587
>>1510769
If it's not a watch press then it is definitely a dick noodler.

>nailed
You mean screwed?
>>
>>1510908
>>nailed
>You mean screwed?
If you nail it, you're screwed.
>>
>>1510483
Sure looks like one. Especially the sighting plane up top.
In use it would probably be aimed at the target then the readings called out to the gun crew so they can match.
>>
>>1510332
I don't know what this is but I do know I want one
>>
>>1511196
Exactly. I think you just nailed it.
>>
>>1511585
just like i nailed your mother
>>
>>1510425
10/10 post, very useful, well done m8
>>
>>1511624
Just like I screwed your sister

Clay pigeon launcher. What do I win?
>>
>>1511867
a real pigeon

Looks like one of these to me.
>>
>>1514016
>Looks like one of these
No, it doesn't.
>>
>>1510332
>>1510483

Too me it looks like old (naval?) artillery aiming device or some aid for it.
You had to calculate your speed & direction, enemy speed & direction, distance, bullet speed....
It would explain why it's stationary. I'm not a native speaker, try fucking with 'artillery protractor', or maybe ask /k/.
>>
>>1514016
Are Americans really this stupid?
>>
>>1511787
It’s better than being the typical American who feels the need to worthlessly answer a question with an uneducated guess.

Duh I think it’s pic related.
>>
>>1510483
I like this. Battle ship gray too. Screws say it is newer than 1930.. I think. Bumping out of curiosity. I used to work around a bunch of 40's military shit and that little non pointy point looks really familiar.
>>
>>1514230
yea, I think this about right.
>>
>>1510332
I have the answer for you, OP.

What you are in possession of is a sort of "computer" for aiming torpedoes, known as a "Torpedo Director". Using the apparatus, a seaman would be able to compute the optimal path for a torpedo given an enemy ship's given distance and speed. Your model in particular is an early Soviet version that would be found on early torpedo boats like the G-5.
>>
>>1514166
>worthlessly answer a question with an uneducated guess.

Its brainstorming which lends to better results.
>>
>>1514166
wtf is that?
>>
>>1514438
>Torpedo Director

Not OP, but cool!
I thought it was some sort of aiming device missing a scope (the top mount).
Found this webby page.

I love old mechanical computers

FINALLY! - Maybe I'll get some sleep tonight...
>>
>>1514503
Are you in the US? Do you have PayPal?
I'm somewhat interested in it. Would you take $200 for it?
>>
>>1514703
I'm not OP.
I'm just relieved to find out what it is.
