Here's a Semi-Professional I just picked up. It needs a bit of polishing, but is in very nice shape, and seems to be all original but for the saddle, a Brooks Pro. Serial # M7E1647?. The "?" stands for something that looks more or less like a backwards letter "C"... could be an incomplete 9 or 0. Strange. So I guess it's a 1977.

I read as much as I could find about these bikes before I went to look at it. If I hadn't, I would have thought this was a repaint, judging by the kinda cheap-looking "Centurion" decals on the DT that are peeling up at the edges. Is that normal for this year? Any suggestions for which glue to use to secure them back down? Thanks for this great resource.
