Arms and Armor Annual...

[Condottiere]

A few bits of info might be dated, since it's form 1973, but it's still a great reference. A shame only one volume was ever produced and I don't think it was a sales issue, as it wasn't mentioned as such in the 1979 sequel series, Art, Arms and Armour: An International Anthology.

BTW, the hardcover and softcover versions have the same ISBN and cover, so confirm with booksellers that they have the copy you're interested in, to avoid the hassle of returning it.

Here's a by someone else and clearly he's not familiar with somethings, as he refers to sabretaches as "vestigial armor".
