I have a T140
It has a ribbed rear drum brake What I want to know is are the ribs tops raw/polished and just all black
Cheers
 
Drum rear T140 would be only two years 73 and 74. All those drums/hubs are polished no
ribs. Did I miss something here?

Could be a conical hub fitted with one of the Manx Norton dress up finned kits I guess?
Or maybe a very late t65 triumph Thunderbird they made in the 80s
That had a drum rear brake
Can't remember if it was finned or not?
 
I can't see that material taking a shine, rust yes.

That is a 1981/2 Triumph TR7T and looks to be the same as the one in the British Spares link in Post #8.

(Off topic, I had a 1973 T140 in the mid 1980's, first 5 speed with disc front brake iirc)

The backing plate looks very much like that off my 1974 Triumph TR5T which of course is a BSA rolling chassis based off the B50 with a factory fit late model T100C type engine.
That finned drum looks BSA derived also.
