A derailleur with an integrated hanger, intended to attach to the wheel axle, would fit. These are pretty uncommon nowadays, but you can probably find a vintage derailleur that would work. It won’t fit anything modern.
If it were me, I’d set it up singlespeed and be done with it

None I think. Looks like its single speed only.

Those are single speed dropouts.
You might be able to fit a internally geared hub. Depending on the spacing between the dropouts.
… Always wanted to try a 2 speed kick shift.

Some frames, particularly old touring franes, are made to use [derailleur brackets](https://www.universalcycles.com/shopping/product_details.php?id=88608), presumably to give the rider the option of using internally geared hubs or other alternative gearing and not be left with a spurious mech hanger. I think that may be the case with this one based on those eyelets, which would be for fender/rack mounting and not typically seen on track bikes. Check the dropout spacing to see if it can accept a cassette/freewheel, and look elsewhere on the frame to see if there are cable stops. If the spacing is correct but no cable stops, you will need to use clamp on stops from e.g. Problem Solvers.

Look for a Shimano SIS hanger (I don’t have the exact part number)

[Here](https://www.redclovercomponents.com/blog/1) is an article that covers this type of thing. I think you’d want to look for an old claw mount.
Give this one a try. Worked on my 80’s peugeot. https://www.amazon.com/SunRace-Shimano-Compatible-Index-Hanger/dp/B001PT8M8C

Non direct rear derailleur
