Trial and error is probably best. 60 degress/58 degrees will probably work the best for an interference fit if you don't have a setscrew to hold the sight in place. If you do, the 2 degrees difference won't make much of a difference with a setscrew.
alternative 2. You can also use a CAD program to draw a variety of dovetails, then print them out, and cut them and see how they fit in the dovetail you are using as your example.
BTW, did you check the Luger blueprints to see what angle is actually specified on the P.08 for the sight dovetail?
The same measurement is probably used for the LP.08, and since you are talking about a sight for NAMBU, which never had an artillery version before, I don't think the dovetail police will visit you if you freelance the dovetail size.
BTW, Dimensions shown on the front sight blade above are IDENTICAL on the blueprints to the dimensions for the dovetail that sight fits into
Also, Someone recently posted the blueprint of an artillery barrel from a published reference book. I don't remember who did it, or what the subject of the thread was, but if you can find that posting, the angle of the dovetail on an artillery barrel is probably in that drawing...
