Well my first thot was sprinkler head but it doesn't pop open. It's a 3/4 X 16 thread. Notice the little Alan head retaining screws. If it gets twisted 90º the head would come off. There is no passage thru it for something to flow thru. The little holes in the head are thru holes from those retaining screws. It needs a 1-1/8 wrench on the nut and shaft so it must have been for some hefty purpose. If that is so what's with the tiny retaining screws? Whole thing weighs about 2 lbs.
My conclusions are:
It has to turn 90º to actuate
It has to handle some humongous force when in use
When not in use the forces are minimal.

Does the head turn ?? Looks like part of the front stearing gear for an antique tractor !! Need to go check our old Farmall cubs !!
But I could be totally off base !!
-
With a 1-1/8 nut and a “3/4 X 16” thread …. my guess would be that it is/was a “leveling/aligning screw” for a piece of heavy equipment.
-
Mmmm,, possibly for the hydraulic lift on a tractor ??
-
Kinda tough to visualize isn’t it?
The head does not turn except if you rotate it 90º it can be removed. The end can be adjusted forth & back (up & down?).
It doesn’t show any hard use like a leveling device might sustain on a tractor. Maybe some other type of machine? Something in a shop?
-
Well,, if part of the hydraulic system it would not show hard use !! The hydraulic lift raises or lowers the equipment up and down !! We have three vintage Farmall cubs !! Late 40`s and early 50`s !!
-
Something about it looks familiar...but just can't brain it up...
-
Familiar to me too but from where or what ??
-
Looks like a pole jack to me
-
I polished up the end cap and the pointed support. It looks to me like vertical marks on the end cap suggestive of a centering device. The support rod looks like it has supported multiple end caps of various sizes. Can't imagine what it might centerup. Something in a machine shop?

I showed this to my husband who was a paint contractor for 30 years. My first thoughts when I saw it was part of a paint sprayer because I've seen him repair them many times. He has confirmed this! He says it is a pump, missing a few parts, to an old paint sprayer. Hope this helps!
-
lol, alrighty then, and there we have it! a pump part!
-
My husband knows his paint sprayers inside and out! I trust him on this one for sure.
-
How tall is this thing from top to bottom ?? Ask your hubby what this thing does ?? A sprayer works on pressure no matter the type !! Can`t see what this could possibly do since there are no hose attachments or holes !!
-
I have to ask just what role this thing might play in a pump mechanism because there is no possible way anything can flow thru it; nothing attaches to it except that the head evidently can be changed.
The head can be easily removed by rotating it 90º and looks to me like another head, presumably with a different angle, can be easily substituted. The circumferential grooves in the supporting conical end suggest great force applied when in use. The wrench size (1-1/8") also implies great force.
The entire thing is steel except the head which is non-magnetic and might be beryllium-copper (just a guess). The vertical marks on the head suggest to me great force applied and if it actually is Be-CU that would make sense as that is tough stuff.
I think the whole thing is slipped into a holder of some sort then run up against something that needs to be centered but for what reason I cannot imagine.
Wow! did I write all that?
===============
Late note last reply while I was typing - the thing is 1-1/4 Dia by 7" long but can be adjusted to about 10" long. Weighs about 2 lbs.
-
Gee Wiz, the thing is, does it really matter? post has slipped into the what is it trivia which is quite a distance from what kind of antique. who cares?
It's a BIRD! It's a PLANE! It's..................

The hole machine is not there. This part is hydraulic and missing packings. It screws to the frame of a sprayer a d the top skinny thing that goes up a and down goes I to a motor. The hole at the bottom of the sleeve is where the paint draws up and then a hose attaches. This is a newer model of what we are talking about.

Now I can't imagine a "spray painting" gun or "spray gun" of any fashion having a need for a 1-1/8" nut and matching 3/4" X 16-threaded solid steel bolt. (I assume 16 threads/inch, meaning a coarse thread bolt.)
You can find a lot of 3/4" bolts on bulldozers, large front-end loaders, etc., but not very many on a "hand-held" piece of equipment or implement. ;D ;D ;D
-
This paint sprayer is an industrial. Not a hand held. See previous post to yours for link to what I am talking about.
-
Jacon4 - I agree. We’ve beat this to death.
Cogar - 3/4-16 is classed as NF or National Fine or UNF (Unified Nat’l Fine) depending on thread depth etc etc. 3/4 dia NC has 10 thread/inch.
I totally agree this is not a paint sprayer part even heavy duty.
Jlsherf- The part does not reciprocate - it is screwed together.
With the head in place and the lock nut tightened it is basically one solid non moving piece.
There is no axial passage for any fluid to flow thru. It is threaded for the shaft which, when fully screwed in, is nearly even with the base leaving just enough clearance for the screw driver shown. Those little holes are for inserting a rod for easier/fsster turning that fine thread.
The pic shows the base end more clearly.
Your linked site showed no spryer pump parts - just whole units.
=====
I’ll stick to the conclusion that it is a centering device which employs various size heads depending on the size of what’s being centered.
Bye.

Jacon4 - I agree. We’ve beat this to death.
Oh Boy! but hey, if you guys are into it, have at it. Meanwhile, I am going with Jlsherf, it's a pump part!
-
Where is Rauville ?? He can usually find these obscure items !!
-
I dunno, maybe vacation?, The only reason i am here is, I am hiding from the heat!
-
I can't believe I'm contributing to this thread, but it looks like Rauville hasn't been around for about 2 weeks...so maybe vacation is exactly right!
-
I can't believe I'm contributing to this thread
Hey! It's an antique pump part man! circa 1988, BAM!
I hope Rauville is on vacation, wishes i was. It's just miserable in the carolinas now unless one has relocated to the coast. How hot is it in Charlotte? it's so hot that at 5 a.m. the "cold" water coming out of the faucet to make coffee is warm!
-
Wow chicka wow chicka wow...BAM!!!!!
That reminds me of that great 90s show, In Living Color.
Hot? In Missouri the "real feel" is 110. I haven't even gone outside today. Our air conditioner will hardly go off (so thankful we've got it) and I shudder to think of our utility bill. Hey, that's my antique money! :o
