If you are interested in Mannlicher -Schoenauer sporting rifles, don't sink hard earned money into that book. If you want an cursory overview of the history of the Steyr gun company and of all the guns they produced, from pocket pistols to machine guns, mostly military ones, it's ok. But sporting Mannlicher - Schoenauers are mentioned on 3 pages only, with some tiny color photos. 21 lines of text is all on the various models from the 1903 (the M1900 and M1924 are not even mentioned)to the end of production in 1973. You will learn more about Mannlicher - Schoenauers from this and other forums than from that book.
