I got a response today from CD. After some more descriptions and measuring we found which one my torch is.
£9 inc postage for the full O ring kit & a bit of silicone grease.
Still in search of a goodmans handle for it though.
CD have stopped making the goodmans style handle for mine now
.
So anyone know where I can get a goodmans style handle to fit an old CD halogen large head umbilical?
