I have to admit I am not very familiar with really old horns. The third clarinet may be ok as long as it is a modern keyed Boehm system horn, and tunes to A=440Hz (that's the written middle staff line B).

The leaky pad issue should be simple for any experienced tech, and it could be may different issues to include and uneven tone hole surface that may need a reshaping.

The very first thing for a student to learn is how to remove rods and pivots so that regular oiling can be done every month or so.

But probably the most important basic skill is to be able to perform both negative and positive pressure tests to truly measure what sort of leaking you have. You take the bottom joint and cover the three open tone holes with your right hand as if playing it. You also depress the lowest pinky key to close off the bottom pads. Then take your left hand and seal up the bottom. Place your mouth over the top and blow for a positive pressure test. This is really only gives you a rough idea how things are going and at some point the "Ab/Eb" pad will blow open regardless of how great everything is. The important test in my opinion is the negative pressure test where you suck the air out of that section. It should hold the air fairly well (kinda as if you did this on a Coke bottle) for at least two or three seconds......more for much better seals.

So I wonder if you could provide an image of the third horn so that even those of us familiar with the model can better see what YOU have.

Finally, since your son has a teacher, what was his input on all of this?
