This second post (see the first part in my Oct. 5, 2015 post) finishes off the list of reference books that I find useful for naval modeling.
First, the Ian Allan series published in Britain from the mid-1960s through the early 1970s:
As it was the first in the series, it doesn't actually say "Commonwealth Warships", but that's what it covers. The rest are pretty self-explanatory:
To cover the Soviet Navy, that the Ian Allan series didn't touch on, I use the following two volumes:
And finally, this is an excellent overview of every navy in the world during 1939-45:
Most of the volumes that I've covered in both parts of this post are still easily available through rare book dealers, websites such as Bookfinder.com, and even eBay. Depending on condition, they can vary from quite reasonable to totally outrageous. However, a bit of patience and continued checking will turn up affordable copies. I hope this helps you expand your library!
