Spitfire Gauges

Does anyone know a source of authentic looking Spitfire/Hurricane gauges ?
Nearly all those available have an airspeed indicator with a double scale that finishes at 350 MPH , whereas even the prototype and Mk I Spits had asi's calibrated up to 400 mph ( necessary when in dives).
Also invariably the Spit panel designers include a double needle tachometer (RPM gauge). Nearly all real Spitfires and Hurricanes had a original equipment single needle rpm gauges calibrated from 1600 to 4000 rpm
