RODNEY HILTON BROWN - AMERICAN POLEARMS 1526-1865:The Lance, Halberd, Spontoon, Pike and Naval Boarding Weapons
Long out of print, this book is still a very good reference on the early European and American pole-arms. Well-illustrated with hundreds of photos. The title is a bit misleading, as the book deals in large part with the early European pole-arms.
Light rubbing to the dust-cover, book itself is perfect, with former owner's ex-libris on the fly-leaf.
