Wow is this a painful discussion of gunshow myth.
Mummed rifles are very common, and the condition of the rifle and the number of assembly-matching parts are of far greater import than a stamping. A rarer manufacturer or better condition example also commands a premium.
At best a chrysanthemum would command maybe a $50 increase in value over a comparable scrubbed example.
Further, a twenty of 7.7 Japanese Arisaka cartridges runs about $22, and the 6.5 about the same. If you're overpaying for Lapua or something, at Gander Mountain, yes, I suppose you might get roped into $30-40 a box, but that's just for lack of comparison shopping.
And the idiot on Sons Of Guns should assuredly not be taken as gospel. Hell, they couldn't figure out the safety.
