Here are some beautiful parts which have been made for us by http://17d-engineering.co.uk/
They are two brake valve handles (one shown with an original for comparison) complete with a notch / trigger and a horn grille.
Both parts were CAD drawn by us and CNC machined from solid by 17D Engineering, the trigger was cast from a lost-wax mold and then finish machined.
The parts were delivered on time, on budget and precisely to our specification and we can highly recommend 17D Engineering to anyone who is looking for precision machining and good value.
