I have a nice set of  Prototype Machine Joe's cantilever brakes for sale with titanium mounting bolts. From what I can tell, these are complete except for one of the black o-rings and the tiny set screws from the back of the cable hangers (see photos). Both of those items could be sourced online or potentially at a local hardware store. It appears that the pad hardware has been filled down to clear the fork blades on one of the sets.

If you do a google search for "Prototype Machining Joe's Cantilever Brakes" the BikePro link has a full description. This set is made up of two front brakes which was common back in the day due to their low profile which is similar to Grafton Maglites.


Please ask all questions before you make a purchase or offer - thanks!
