I was just thinking about bronze again, as Kane mentioned. I had a metal sculpture class in college & did alot messing around with bronze which the universal is 90% copper, 10% tin. Now when we did our sculpts, we could any number of different patenas on a piece of finnished bronze that would give different characteristics. You could use one that made it look almost gold, another that made it look very dark..almost black, annother that made it very red, almost like copper, and they even had one that would turn it completely green like the statue of liberty. I dunno where I'm going with this.....LOL Oh: it does look like some of the rocket cones are more brass/gold colored, while some pics look copper colored. I wonder if they used bronze & maybe patenaed them??? Might explain why some rockets look differnt than other in differnt pics. I dunno if machinists can work with bronze though???? Heck, I have no idea if LFL would have bothered monkeying around with a patena in 1978 either??? LOL I'm just thinkin out loud here.
