Thanks everyone for the additional responses. I got on the bike for the first time yesterday. It feels great. I know this is going to be a special bike.
55/Rad, thanks for the kind offer, so far I'm good, if I need any of those parts I'll let you know.
T-Mar, Many thanks for the additional information and all your support, especially the comment about the tubing, that's good to know. I didn't realize the levers were dia-compe, I just thought the Shimano 600 logo wore off, but no problem cause I'm evaluating whether or not to go brifters with this bike. The previous owner did provide the original pedals and an additional chain ring, I just didn't include them in the pics.
A.Winthrop, thanks for the information about the shifters. These are working fine right now. I want to ride this bike a few times to make sure I'm comfortable with it. If I decide this is going to be a main rider, and that is my hope, I will convert it to brifters.
Again, thanks to everyone for your comments and support.
