mh fairly it is a rare and unique item BUT
if it is teh plastic version with broken cable missing sender you can only yuse it for display...
i do restaurationservice on gauges like that, i change the gauge itself to the metal version, ad a new indicator, ad a new cable, and i can provide also sending units for this kind of gauge.... what can be kept is th echromebezel, fgauge face and lamp + trim...
if the housing is not broken, i can ad also a new cable.....
post pictures of the backside and i can tell you what your gauge is worth...
