profile sprocket history thread?

[newlovetattoos]

Did we have a thread up a while ago with a kind of timeline of the different profile sprockets and when they were released or did i dream it? I cant find it anywhere so im worried it mightve actually been a dream.. a really boring one

There's a thread about profile sprockets in the mid section reference section if that's what you're thinking of?
