When I originally bought TS23677 back in about 1985, it had one straight ported cylinder, and one angled, which also had the adaptor fitting on it. I assumed that the angled one was changed along the way. Since it was on the brake master side, I rebuilt that one (as the bore and piston was in very good shape) and used it for the clutch master and bought a new master for the brakes. Both of these cylinders now have the angled fitting with the adaptor.
Unfortunately, the day I decided to put a post 60k body on TS23677, all ideas of originality went up in smoke. :laugh:
