Go to surplusrifle.com. A wealth of information lies therein. Of all my surplus rifles, The K31 is my favorite. Next is my mauser with many German markings. In Mosins, a 91/30 round top receiver in standard wood, and laminated. An M38 Mosin with an actual M38 stock(most have a M44 stock with the groove for bayonet. An M44 Mosin in standard wood, and laminated. A Mosin 91/30 with Hex shaped receiver. A Yugo 8MM Mauser model 24, and a model 48. A Japanese rifle of which the model number escapes me at the moment is also inexpensive. Todd, at FamilyFirearms & Finishing is a good place to buy, as he will not sell anything that he would not keep in his own collection. He is slightly more expensive that Aim, S&G, etc., but his rifles are hand picked. Most rare surplus rifles are in the hands of collectors and rarely appear on the market. If you haven't applied for a C&R license($30.00), I would recommend doing so. Enjoy.
