I picked this up a couple of months ago and I'm just now getting around to posting pics. The serial number is half filled with paint but I looked it up (about a couple months ago) and decided that it's probably an '83 613. It seems that there are a brazillian different variations on the 600 series and some of them kind of split hairs so I'm not really too concerned about actually IDing this thing, just wanted to show it off.
Does anyone know what brand the (rusty) top tube cable clamps are? They're about the only thing I'm gonna replace.
The guy said it's all origional exept for the itty bitty third chainring. I think I'm gonna leave that on, though as I just moved to the hilliest part of the Hudson Valley.
