Hi Guys! I'm a single edge shaver, but found a couple of old straight razors when cleaning out my Dad's attic. One is a "Blue Steel Extra" M.I. Germany Imported by H&H Grinding Cleveland Ohio. The other is a "The New Improved Eagle Razor" Imperial Razor warranted Registered 20507 Germany with a flying eagle engraved on the blade. Both have a little rust spotting. Are these valuable or collectable. If so, what's the best way to sell them. Dan
