Wondering if anyone out there might have some original Universal brake blocks (in the nutted holders), the reddish ones (assuming that's the right block for the year). I've seen some that seem to have string or something embedded in the rubber and others that seem pretty much straight red rubber. These would be for my '64 Legnano Gran Premio that sports Universal Extra sidepulls if that would help determine what's 'correct'.
Thanks for any tips,
