More accurately, I ordered Duncan Crow's book, British and Commonwealth Armoured Formations (1919-46). I was pleased at the price, and I hope the book is in reasonable condition. I search using used.AddAll.com exclusively, although you purchase your book from whatever organization is offering the book. In this case, I interacted with Biblio.com. I have wanted this book for years, but only in the Internet age is it possible to find and purchase books easily.
