I could not find a appropriate forum for this so I'm putting it here. Anyways...

I just saved a Schwinn Le Tour out of the garbage of a fellow neighbor. At its present state it is a 10-speed, but I'm planning on converting it. But I first wanted to see if I could find out the date of it (curiousity). I looked all over the frame but the only place with any type of number was the bottom bracket. First at one place it has a "B" off to the side followed by nothing. The it has "W8677" in the center of the bottom bracket. Now you my also note that the crank set says "Japan" and the brakes are Wienmann (they no longer make brakes). Also all the decal have been removed and the bike has been repainted at least 4 times, so the only way I knew it was a Le Tour is because the cranks have "Le Tour" endented on them.

Thanks for the help
