The widely accepted model for the diagramming of atoms today is the Quantum model, which involves different orbits holding two electrons, and different energy levels, hold electrons in groups of 2, 8, 18, and 32. Drawing this model typically results in a huge mess of lines, and a three dimensional model would be even worse. So i suggest using the Bohr model, and making a semi-sphere with the correct number of electrons in each shell.

Additional information is necessary to properly value your rifle. There were two models available in the Winchester Model 1906. One had a straight stock and the other had a pistol grip stock and was called a Model 1906 Expert. Which one do you have? Also, you did not say, if your rifle was partially trimmed in nickel or was fully nickel trimmed?
