I'm just guessing here, Craig, but I suspect that 177 of the folks that viewed your question DIDN'T KNOW THE ANSWER! You got an answer about the colors.....seems to me the question about dates and compaines is anything but simple, and something 95% of Oldgassers don't know....I certainly don't. And I think the "something you're missing on this site" is that participation is voluntary, and that chastising folks for not answering your questions isn't the best way to get information. But that's just my opinion.
