That'll turn out really nice. It's anyone's guess as to why they didn't come with touring gearing from the factory...

Did the previous owner have to modify the rear brake to get it to reach? Looks like the front is already at the bottom of the slot. I tried Campy sidepulls on my '67 Carlton 'The Flyer,' which is very similar to Internationals, and the rear wouldn't quite reach down to the 700c wheelset I was using. It was so close that it probably would've worked with 27" wheels.

Are the bottle braze-ons stock? I didn't realize they could come that way.
