I've had mine for about 15 years and paid $40.00 for it. Mine is without acceptance marks and is the Navy model. When I bought mine there were 2 with USN stamped for $10 (25%) more and one with USMC for $20 (50%) more. These were in very good condition (no broken blades and the main blade sharpened but still in original shape.) Knives with broken saws were about $25 regardless of model or marking. I have never seen the pouch, and assume most people carried them in a pocket, but they'll pull your pants down in a hurry. Ivan
