I like Jaegers and I have made quite a few of them. The shape Taylor is speaking of is easy to make, but you have to understand what is needed. The "cheek" of the stock (wisest part of the round or oval) Should be at or very slightly above the level of the bottom of the barrel. So if the pins are touching the bottom of that barrel the "cheek" should run right through the pin holes or about 1/16" above them. Not below and the cheek should be something you can easily see and "put a finger on". If the gun has a bit too much square shape you'll find the "cheek" is not distinct.
Here are a few pics. As you can see, in looking a pictures it very hard to see this cheek that I speak of, In most cases the sides of the hand-rail section of ther stock looks flatter then it is on the gun. I have seen this in most pictures, including those done in the books we buy. But if you look at the lock moldings and in your minds eye see the widest part of the stock NOT coming from the center of the molding, but coming out of that molding in line with the pin holes you'll start to understand what I am trying to say. It's very hard to show it with a picture.
I hope they are helpful. Maybe not, but This description and these pics are about all I can try without putting an actual gun in your hands.

This is not a Jaeger, but I got luckier then I usually do in the lighting, and you can see the cheek easier in this pic then you can in most. It looks like it runs right through the pin hole, but it's actually about 1/16" above it.

This one is viable if you know what to look for.

Again, not a Jaeger, but the lighting shows what I am trying to describe.

I apologize for my poor skills as a photographer, but maybe I can get the point across in-spite of my limitations.
