Can anyone give me some information on the following two books?

BATTLE WEAPONS OF THE AMERICAN REVOLUTION
by George C. Neumann

SWORDS AND BLADES OF THE AMERICAN REVOLUTION
by George C. Neumann


Do these books replicate each other in showing the same examples of weapons (photos/information etc)?
If so how much is replicated?

Does BATTLE WEAPONS OF THE AMERICAN REVOLUTION provide dimensions and weights of weapons like SWORDS AND BLADES OF THE AMERICAN REVOLUTION?

Sean Flynt recommended I purchase SWORDS AND BLADES OF THE AMERICAN REVOLUTION which I intend to do shortly. I'm also thinking of purchasing BATTLE WEAPONS OF THE AMERICAN REVOLUTION, but I don't want to buy it only to find out the majority of the examples of weapons featured are already shown in SWORDS AND BLADES OF THE AMERICAN REVOLUTION.

Thanks

Danny
