It does have two braze-ons on the rear of the seat tube, im thinking maybe for dynamo wires?
It had a front rack attatched with a wired halogen attatched so maybe there was one on the rear aswell (wires were cut)
Also you can see theres a hole under the bottom bracket, this is were it had a modern plastic gear cable guide fitted,so the cables ran underneath rather than use the braze-on guides above?
The cable clamp must of been used rather than the braze-ons also, i removed it when cleaning it up and put it back on the wrong way round
so i dont lose it.
