Looking at this pic of BB, and it seems to me that the braze on cable guides are missing, and those stubs are all that remains.
I can’t see any evidence of them anywhere else on BB, and certainly no holes for the press in rivet plastic type.
Maybe I’m missing something and you learned types can fill me in on a type of cable set up I,m unfamiliar with. If it is indeed Chromed underneath that would make rebrazing new ones difficult without compromising and discolouring the Chrome I suppose.
maybe a S/S candidate.
Actually they look like they have holes through them for the cable to run, much like the 3rd one closer to the chainstays in that very picture. Nothing to worry!
