Thanks, mrblaine - Looking at their website, they're an "old school" plating company. Not many of those left. That is a true hexavalent process, which is much more durable than trivalent, and it's OD green, to boot! The Europeans decided that the trace hex chrome washing off fasteners in cars needed to stop, and that decision changed the plating industry over a very short period of time. Since then, most platers converted to trivalent (or other processes altogether different), and the hex guys are few and far between. The movie, "Erin Brockovich", was partially responsible for this rapid abandonment of hex chrome. I'm putting that one in the "Rolodex!"
Also, you weren't kidding - I'm a rank amateur...
