Double Bass Peg box crack repair

I returned the Kay school bass and immediately have another question. The next one is significantly better than most at the middle school. I think I can handle it but want to be careful.
These are no budget (my pocket for anything required).

It appears to be a 5/8 carved bass (~39 inch) made in Germany for US export.

The paper tag inside says:

Georg Anton Schuster
Geigenmacher
Wien Ann 1788
Made in Germany

In what is likely ink (hand marked), the number 1143 is also on the tag.

I'm thinking ~60 years old "factory".
Mostly curious (there is at least one old thread) but I don't want to misunderstand the value. If it is way over my head, I would give it back.

It has some rib and front cracks with previous repairs - many now open again. The back is two pieces and the center seam is opening, some cleats on the inside have fallen off.
Edge seams are apart all over which is what the teacher noticed. They took off the bridge and set the bass aside. Some get played until the end block breaks free.
Overall, it is not very beat up considering it is in a school (no student carvings, no holes punched through the ribs, ...).
One bout of the top is completely loose already. So, I think I can deal with the cracks/cleats with the front removed.

There is a horrible hard tail wire just twisted to connect the two ends and the bridge needs to be replaced. Big box store cable would be a cheap improvement?

Anyway, I'm running on here, the real question:

The problem I am very uncertain about is in the peg box.
There is a crack (with a small gap) on what appears to be only one side at the very top. It runs between near the corner and the upper peg hole (gear side). The top two machine plate screws may be holding it from opening more. I don't see any evidence that it was dropped like a big chip out of a volute.
The rest of the neck looks fine (nice figure but a bit thin with a glossy finish everywhere).

Attached is a close up picture but it is still hard to see the crack (string is still on)

This is not totally failed. Is it likely to get worse?
Should I just leave that alone?
Only push some glue into the crack?
Or do some more extensive repair, perhaps under the plate?
I did what I would call a "cheek graft" once on a violin.

As always, thanks for any suggestions.

I would most likely glue and clamp that little crack. It was probably caused by too much string on the one side of the capstan wedging the cheek away as the string was tightened... You could dowel the repair but it shouldn't be necessary - there's no real stress on that part of the pegbox.

Sounds like you've found a nice one - Good luck! ;)
 
I worked very slowly on this one.
It's a nice little bass but I didn't see all the problems at first.

When I took the top off, I found there was white glue all over it.
Long drips running all the way to the bass bar. Sad.
Besides the cracks I knew about, the end block was nearly detached and there were pretty large chunks of the front inside edge missing from old repairs. Inlay patching is hard.

As for the peg box crack, I think the string winding may have been the cause. It was wound many times and hard against the side. So, I only glued it.

Anyway, I have to post the final pic.

Thanks
