Here's a question for the gun smiths out there:
What is the name for the bluing on older guns that has a multicolored appearance?
For example, a lot of "replica" guns like Ubertis have this appearance (http://www.uberti.com/firearms/stall..._bird_head.php). I figure there's probably a more precise term than "that colored bluing" and want to educate mysefl! Thanks!
