I'm thinking of buying an old K98, do any of you guys know much about them? The one in particular that I'm thinking of buying is stamped DCB and at the bottom it has a 4. Is this a good thing? The guys says all numbers match except the magazine baseplate, and all markings are intact except for one which is de-faced. he's asking for 650 for this gun, is that reasonable? I'm in Canada if that makes a difference these days..
