The new Freeman is the new publication from Chris, it's an updated version, have a look here for a list of all the books that are sold by Chris (including that new Freeman)
I would definitely recommend that, and the following;
- Gouby (http://www.michael-coins.co.uk/) I believe you can buy them directly from him, ask him to sign it if you do
- Groom (a forum member here) you can buy his book here > https://www.amazon.com/Identification-British-Century-Bronze-Varieties/dp/1409285502 and is a must if you want to seriously get into varieties, it has a lot in there that the others don't cover
You can get Peck, it's a great book but most is covered in these 3 books. Depending on how far back you go, there are other publications like Jerrams' study (I forget the name) on early Victorian bronze or Bramah (but I think that's coppers only).
The first 3 will get you where you want to go for now
