Help identify vintage movement

[Pika]

Sorry I don't know anything about watches but I am very curious about what this is that I've acquired, it is parts of a Rolex watch
When I tried to check for 4389 it does not seem to be on any list of known movements.
The serial number is 440141, but it's not behind where the bracelet would be, but rather on the back case.

If anyone knows about what kind of watch this is and what year I would appreciate learning

The movement is one of the 10 1/2 Hunter series, probably from the mid 1940s and it is a manual wind, 17 jewel version with a center second hand.

Later versions of the 10 1/2 Hunter series were developed into the 700 or 710 movements.

Finding the missing parts and then getting everything to work properly will be very difficult, even for a specialist, as there were so many different variations of the basic movement and not all balance assemblies and associated parts are interchangeable.

One photo shows a small perpetual rotor and that is from another watch not related to this movement.

The inside of the case back has a model number, 4365 I think, and that would be for a very early manual wind Air-King. The movement might have come out of that case as the dates are roughly consistent, but it might also be that the movement and case are not related and you've got a watchmaker's or jeweler's lot of parts that have been cannibalized to repair other watches.

If the movement and case are related then it might have been something like this one:

but whether you could reasonably expect to have this one built up into a complete functioning watch would be a question for the very few watchmakers still around who have experience with these 60 to 70 year old watches.

One member of the forum (R.W.T.) used to participate in discussions about this type of movement and had a lot of experience with them, but he hasn't been around for quite a while, last posting in early March this year.

This is about a similar movement, and the contributions from R.W.T. were very helpful to the OP:
