I just bought a copy of The Fred Jane Naval War Game (1906), which is interesting in its own right, but this 2008 edition edited by John Curry includes a lot more than the classic naval game by the famous man.
Also included are:
A brief bio of Fred T. Jane by Curry
The 1906 rules by Jane, which represented the game in its mature form.
Some "Fast Play" rules by Jane
The Royal Navy Wargame of 1921, which was the official RN rules for board exercises
and finally an interesting historical piece from 1914 "Your Navy As a Fighting Machine" by Fred T. Jane.
All for under $15.
