It is not a control column but it is almost certainly part of an aircraft control system.
The part numbers do not ring any bells for me though.
There are several inspection stamps visible but none are readable. Better photos or good clear drawings would help of these and other stamps. These stamps on castings could be the casting contractors stamps. Part numbers and stamps on the tubular section would help as those would be from the airframe manufacture

Looks to my like some form of flight control cable bell crank. Look at the sides, that looks like where a control cable will rest inside.

Rudder control bell crank for a larger aircraft was my first thought too.
That is exactly what I am thinking.

The oval inspection stamp under the 240-35xxx part number is listed as a Lockheed stamp and is known to be on C-121, T-33 and F-104 parts. Size would indicate maybe a C-121 series part, but I don't have any IPB's or access to any for the -121.

It is actually a dual control part - note the inner shaft assembly also has a cable sector on it. Rudder and tab? Elevator and tab? Something else?
Lockheed numbers of the period are usually six digits.
Lockheed built parts for other manufacturers and complete aircraft such as the B-17 so do not rule out it being for a non Lockheed product. Boeing part numbers in the 30s and 40s had absolutely no pattern or logic so it could well be a Lockheed built Boeing part.
The part number layout suggests NAA as they use a model number followed usually by a five digit part number. The NA-250 would probably be a 1950s/60s aircraft.

I'm sure I've seen this manufacturer's logo (or a similar one
) before. What does it say below?.......PROCESS
This is obviously the name of the part manufacturer contracted by the aircraft company. It might give a clue what is this part.... I guess.

Given the large number of Vs there I begin to suspect a Vought product or design. I was originally inclined to Vega (Lockheed).
BlooDLioN - any chance you could lay a piece of carbon paper over the big logo and ***** process and lightly rub it to transfer the ink to the high parts and make them clearer? Try the carbon paper on something else painted first to make sure the stain is not permanent. If you are not worried about staining a small stamp pad lightly pressed on them would also work. Food dye is not a good idea - it is often very permanent.

As mentioned in the same table with inspections stamps, this particular one has been found on Vertol CH-47 as well.

Looks like "Osborne Process" to me or something like that.
The letter after B is not O for sure - compare with the other O-s. There is not enough space for RNE at the end. It's either RIE or only 2 letters. IMHO.

Taking a stab in the dark but maybe a rotor head and mast base?
No, there is not a helicopter mast similar to that. That thing could not handle the torque a helicopter rotor head is subjected to.
It is 100% some kind of flight control cable bell crank. Just which flight control (I suspect rudder or elevator) and what aircraft is the question at this point.

Great, you nailed it
: here is a description of the R.H.Osbrink Manufacturing Co.The Osbrink Process is a precision sand casting.
The letters in the triangle are R.H.O.
