Gary D is correct. The early rifles are technically Model 1892s, but are not marked "Model". They only have a (fiscal) year of manufacture stamped on the left side of the receiver. The Model 1896 rifles and carbines appeared in 1896 and are so marked.
I am told that Joe Poyer put out a Second Edition which corrected a lot of the perceived errors in the earlier edition. Price is in the $20 to $25 range (and readily available on line) as compared with $100+ for the Brophy book and almost $200 for the remaindered Mallory & Olsen books. If you think you need one of the expensive hardbacks, the Brophy book is a far better value.
If you are after a cast bullet hunting rifle, stick with the much more common US-made Krags. Stick to the 30/40 cartridge. There are wildcats and conversions to other calibers which can lead to problems. For a hunting rifle, the "no drill" receiver sights will be worth the search. The Redfield models are the best, followed by the Pacific, with the Marble sight a distant third.
I also participate in the Krag Collectors Forum. My particular interest is in the .22 rimfire conversions. I did not pay $10.
