OP here:
Yes, it is a slender, nominal 1" top tube, part of the reason I'd like to get rid of any plastic housing along the length of the gold anodized finish, as have the brake cable mimic the der cables on the down-tube. As for what God intended, it isn't clear she intended epoxied joints to last, in use for 36 years. Engineers have suggested I have the bike flux-dyed and X rayed before riding, something I would not expect to be able to pay for prior to the crash that damages -- or is suspected to have damaged -- the skeletal parts of my own body.
Kim: Thanks for the Rivendell ref. What with the contemporary frame world gone to plastic and oversized aluminum, I wonder what those strong Tektro-looking clamps might do to the tubes they could be over-torqued to, but that's an off-topic wonderment.
I wrote "tinker-toy Alan" with modesty, because while it was the first fine frame I owned, I appreciate that on this list it is an accident of timing that bikes of Italian engineers whose joinery expertise was in the chemistry of screwing-and-gluing with soft-polished lugs are not off-topic.
I appreciate concern for soft-braking. But, it is the rear brake, where softer but not total loss of braking would be OK. Still, I get the point.
Private offers of sales for a pair of new or used cable clamps or clamps with stops, packed between a pair of cardboard pieces in a first class mailed envelope gratefully accepted.
